<shudder> ... as the guy that forwarded this to me said, this sounds
like a freaking security alert, not a product announcement. Bend over
and prepare to take it from the man (you'll like it too because it'll
come in 6,458,345 colours *and* show pretty animations).

Frenzy Begins Over Cookie Alternative
By Zachary Rodgers | March 31, 2005
An existing technology offering cookie-like functionality is gaining
attention from publishers, marketers and others as a possible
replacement for the ubiquitous, but potentially endangered, text files.
The technology, based on Macromedia's Flash, is getting attention as
awareness spreads of an apparent increase in user deletion of cookies.
A JupiterResearch study recently found nearly 40 percent of Web users
clear these text files from their machines on a regular basis. Because
of the enormous consequences of cookie deletion for online marketing,
analytics experts and ad technology vendors have since begun overtly
addressing the potential of the "Flash cookie."
The technology is based on a feature of Flash MX called "local shared
objects" (SOs), which can easily be placed on a user's machine by
adding a piece of Javacript to a Web page. SOs are similar to cookies
in concept and function. The main difference is Web users don't know
what SOs are, and are therefore unlikely to delete them. Additionally,
commercial anti-spyware applications do not typically block these
files, as they do cookies.
Among those discussing the potential of SOs to identify returning Web
users is Eric Peterson, the JupiterResearch analyst behind the cookie
deletion study.
"It's feasible," Peterson said of the technology. "Local shared objects
[are] baked into the most current release of Flash MX. It provides, via
Javascript, the ability to communicate between the Web application and
the visitor's [browser]."
In fact, the Flash cookie can store a much wider range of information
in a user's browser than the traditional cookie, according to John
Quarto-vonTivadar, CTO of Future Now Inc. and co-chair of the Web
Analytics Association's technology committee.
"SO's can store many orders of magnitude more information than a cookie
can and are also not affected by browser settings but by the Flash
player settings," said Quarto-vonTivadar.
"Most people aren't familiar with how to tweak their Flash browser,
though I suspect that would change over time," he added.
At least one ad technology firm is already testing marketing
applications of the Flash cookie.
United Virtualities, a vendor of rich media technology, is today
expected to introduce a product that employs SOs for user tracking
purposes. The company's platform is called PIE, which stands for
Persistent Identification Element. For use of the platform, UV charges
a .03 CPM.
"What we have done is made SOs very easy and practical to use," said
Mookie Tenembaum, the company's chief executive. "What it does is make
the cookie persistent. If they use the PIE system, it's a Javascript
tag they put on the page, then the cookies are never erased for
purposes of identification."
Tenembaum added, "Instead of cookies now you have a pie."
Jupiter's Peterson wouldn't speculate about the value of such a
product, which manages SOs that support ad campaigns on publisher and
network sites. Neither would he explicitly endorse using SOs for this
purpose, out of fear that widespread use could result in a consumer
privacy backlash.
"For companies that can independently verify that cookie deletion is a
problem, it's certainly worth exploring," said JupiterResearch's
Peterson. "I don't go so far as to recommend using it, because it's one
of those great unknowns. As good as I feel pointing out this technology
flaw, I would feel really bad if Macromedia [was compelled to withdraw
the capability]."
Interestingly, SOs owe their existence in part to the cookie.
Macromedia initially added them to Flash MX so developers of Flash
movies and applications could identify and obtain data on returning
users without cookies, which were awkward to integrate with Flash. That
the technology could end up replacing the cookie did not seem likely at
the time.
Macromedia appears somewhat wary about the use of SOs for tracking
online behavior, particularly for marketing purposes. The company has
issued a statement advising Web users on how to disable the automatic
placement of SOs on their machines.
