Red5 over HTTP?

Hi,

In cases where client is behind the firewall, can RED5 be tunnelled over HTTP like XMPP BOSH?

I’m not sure whether client firewalls allow outgoing RTMP messages.

Also, can you recommend a consultant/service provider that could customize Desktop Sharing application?

Yes, you can tunnel RTMP over HTTP (RTMPT) and the embedded Red5 server can be configured to do that. However, you would need to customise your Openfire server to run Redfire from the http-bind root web service.
