[streaming] stream flv behind NAT

[Daniel Pek]

Hi!

I'm really new in vlc, and I have a problem. The scheme i would like
to "implement" is the following:
clients should put their streams (maybe behind NAT) to a central
server, which broadcast them
the source of the streams are wavs, or any kind of formats, which
hardware digitalizers can produce
the broadcasted streams should be valid flv (with or without video
data) to display them in web-browser in flash-players
with a little ascii art:

src1 o---|   |   ___    ________
         |   |  /   \   |      |
src2 o---|NAT|--|NET|---|Server|---* broadcast on http://server:port/stream.flv
         |   |  \___/   |______|
src3 o---|   |

src1, src2, src3 are wavs, or any other (tipically mpg) stream. They
should connect to Server, and put their streams to it, and the server
should be able to identify the streams by something (maybe an ID), but
i don't want to use more than one port. If i have the streams, i can
transcode them to flv, this is not a problem. So which protocol do you
recommend, and what's the best solution for this situation?

Thanks for help in advance,
Dani
