What do you think about using these logs as an overall storage  
mechanism for projects/docs? Maybe not now, but in some time in the  
future?

Do you imagine an interface to TamTam? TamTam uses the greyscale  
mode, btw. will Etoys be available in greyscale mode also?
http://wiki.laptop.org/go/TamTam

I guess the easiest to interface to TamTam would be to emulate python  
commands sent to the CSoundServer as found in:
http://dev.laptop.org/git.do?p=projects/ 
tamtam;a=blob;h=f3adc4b19f2b7352535c1e805065eee1d830f265;hb=697021638dd0 
c608e58f95b3a9e2fc4461aa53be;f=Framework/CSound/CSoundServer.py

We needed to emulate the notes according to:
http://dev.laptop.org/git.do?p=projects/ 
tamtam;a=blob;h=40a19e5054bce50b7c189cbc176073ae3a685a20;hb=697021638dd0 
c608e58f95b3a9e2fc4461aa53be;f=Framework/CSound/CSoundNote.py

Don't know why they don't use OSC instead -- funny thing to send  
_any_ python command over a socket to some other machine (exec !)...
Looks like Etoys could then play tunes together with TamTam, even  
sitting on some different machines... :-)

BUT: If you "only" wanted to create MIDI files to be played by csound  
you might want to have a look at
http://minnow.cc.gatech.edu/squeak/1406#Audio

which gives you a MidiScore to MIDI file writer by Yisrael Lowenstein  
(Squeak 2.8 though, and beta, and I haven't tried it).

Cheers,
