Best Flash Audio/Video + Interactivity server?

Question

I\'m looking for suggestions on Flash realtime servers. Currently, we use a combination of Moock\'s Unity and Red5, but there are a couple problems. First, we are moving to AS3,

Answer 1

I vote ElectroServer - it's pretty stable, reasonably priced and I've met the guy who runs the company and he's a swell guy!

1. Stable - YES
2. AS3 support in client libraries -YES
3. Can extend server-side (with Java or other languages) - YES
4. Supports real time audio/video from flash clients (eg webcams) - YES
5. (not required, but very helpful) Some method of communicating when all traffic except HTTP or HTTPS is blocked. Eg RTMPT (tunnels RTMP over HTTP) support or similar. NO - BUT WILL BE SUPPORTED IN NEXT VERSION
6. Reasonable performance, I'd like to get at least a couple hundred users connected without killing a server. YES - EXTENSIVELY LOAD TESTED WITH THOUSANDS OF USERS
