I hear you

I've tested twinkle and it worked quite well for point to point calls.
Both it and ihu could probably be modified to accept appropriate
parameters to operate within the Sugar context if needed.

I'm also aware of someone working again on the point-multipoint audio
idea that I tried out a couple of years ago ... a press-to-talk (PTT)
multicast portable radio emulation.
