[osflash] RTMP protocol handshake data

[Chris Allen]

Yves,

Please keep in mind that you entering some very shaking ground in
terms of the legality of disassembling binaries that Adobe has
written.

We the Red5 team have purposely avoided doing any such thing for this
reason. We have in every way made sure that we are complying with the
law and the legal agreements that Adobe has published. Please see our
statement on discovery through observation here
http://osflash.org/red5/discovery?s=discovery+through+observation for
more information on our process.

I just wanted to make it very clear that Red5 and it's team members do
not condone finding information on RTMP, the Flash player or the inner
workings of FMS in this way.

Red5 Co-Project Manager
