An easy answer would be : as cross-platform as possible !

Sure.

You forgot one of the best multimedia platform : BeOS. It's still not dead. And
when it will be fully rewritten (OpenBeOS) it should have a great second life.

You mean how to pass the buffers ?

I think the cross-platform C calling convention is determined by the OS.
Do you plan to export :
- 1 function dealing with lots of messages ?
- many functions dealing with one particular thing ?
For sure, C is the most portable language. I feel a bit sad noone is ever
stepping into the object oriented world of programming. That would allow
building standard classes that everybody could use, and concentrate on the
"real
work".

Maybe to have an Hardware Accelerated Layer ?
