[asterisk-users] Conference solution to handle 10, 000 participants - possible at all?

[VisionVoIP]

Hello list,

A client is asking to setup an asterisk based conferencing solution 
which could handle 10,000 participants (in one single conference or 
combined in multiple conferences), and later could be scaled to handle 
up to 50,000 participants. All callers will be over SIP, using g711.

I have designed and implemented MeetMe based conferencing solutions 
before but nowhere near to this scale. Is it possible to do this at all 
using Asterisk? If yes, wow, but how?

Even a powerful server will only handle up to a 1000 concurrent g711 
calls, maybe a few hundred more. Going beyond that will require scaling 
to another server. But since MeetMe will be running on the first server, 
how will users from the second server join it?

Any ideas, suggestions and experience to share?
