a-DOH-bee AIR 1.5 on Linux

"Today, we are very pleased to announce the availability of AIR 1.5
for Linux. Thousands of AIR applications such as Twhirl (a popular
Twitter client), AOL's Top 100 Videos, and Parleys.com, are now
available to millions of Linux users. This announcement also means
that web developers can now use the AIR SDK to create a single desktop
application that works on Linux, Mac, and Windows without any
changes."

Looks like Linux, 32-bit at least, is nearly to the point of
simultaneous releases of AIR with Win and Mac.

64-bit Linux can run AIR 1.5 as well on the alpha Flash 10 runtime.
