What whould be a good cross-platform development kit for WebRTC?
By good I mean:
- it provides interoperable libraries for developing for Web, iOS and Android
- supports audio/video chat in rooms
- preferably free/open source
- one time payment for SDK is OK, recurrent payment per minute/traffic/storage is not; budget would be in the order of thousands
- support/fallback for IE & Safari on web (but this is not mandatory)
