Flash does support interactive audio/video, not only streaming. And there is a new protocol called RTMFP in flash 10, which is on top of UDP.

And if it does, it's not necessarily enough. The Flash multimedia API is at least in Flash 9 very restrictive and only allows embedded or HTTP streamed media, which is both rather useless for VoIP applications. If there's not API for UDP (I suppose there's not), you won't get very far, even with native Speex support. Tor
