[IMC-Video] flash player recipe

[Mick Fuzz]

I totally agree on using our networks of contacts and
technical expertise to put together a project like
this for video.indymedia.org - i guess let's get there
step by step is a good way to go forward. 

We are going to have a meeting in London to follow up
from the transmission.cc event in Rome. In rome we
were talking about all the kind of stuff mentioned
below. the dates are 13, 14, 15 of October

It would be great to see people in IRC for that
meeting that can't come in person. I'll keep people
informed and send out the invitation in a few hours.
