I intend my next several realtime Csound projects to also be OPLCsound 
Activities. First I'll do the traditional Csound part, then adapt them to 
OPLCsound.

However, from the beginning I want to be clear about both the limitations 
and opportunities of XO.

So, the following queries:

1) In terms of opcodes, complexity, etc., are canonical and OPLC Csound 
different? I'm aware that: a) FLTK is not available; that it's place is 
taken by Python and Victor's csndsugui; b) that realtime complexity must be 
limited. Latency will not be an issue for me, and I *assume* that if my 
instruments are relatively simple, and their number limited, I'll probably 
be OK.

2) I assume sensekey works; I may well try to limit myself to the ASCII 
keyboard instead of getting into on-screen widgets. In this regard, has 
anyone tried to do (UDO?) a custom version of sensekey for the OLPC? 
Especially one that incorporates the OLPC's unique keys and screen-side 
control buttons? I've no idea whether theuttons se keys/b have ASCII 
equivalents or not; does anyone know, and if so, what they are?

3) Are there any standard alternative controllers being developed for the XO 
platform that I should know about - designed especially for the young?

Any other advice, or pointing me to related resources, would be most 
helpful. I want to get started on the right track.
