[Red5] Adobe's private version of Flash supports Accoustic Echo Cancellation and Screen Sharing

To answer the question about the plugin / download:

Acrobat Connect Pro runs either in "normal" or "enhanced" modes. The
enhanced mode requires a "plugin" downloaded from within flash. This
"plugin" is just an EXE file that gets executed when the appropriate command
is issued so it could be anything. In this case, its a flash stand-alone
player with lots of extra goodies like screen sharing and echo cancellation
that no-one else is allowed to use.

My guess is that Acrobat Connect Pro team wanted to use screen sharing and
echo cancellation but flash didn't support it. They forked the flash code
base (evidence of this is that the Acrobat Connect Pro executable contains
references to AMP - Adobe Media Player. This is another "plugin" that adobe
has recently released.) and added what they needed. To avoid get the thing
out without causing security problems, they only allow signed SWFs to run. I
used a hex editor to look at the files in question.

My issue is that since adobe have already added support for these features,
how can it claim flash is an open platform when the best of its features are
only available to in-house projects it deems as legitimate.
