...yeh, but instead of a rightclick on the node, I was thinking of  
sending a [edit< message to the object (keeping with "the pd way"),  
and that would open a text widget window, perhaps even on the canvas  
like ben's [entry]...speaking of which, I checked that out briefly,  
and it seems pretty nice, but I couldn't get it to print any output  
on bang...time to look at the code...

...that spec looks very similar to CgFX project files, but I don't  
know of something similar yet for glsl:  perhaps we could quickly put  
something together with XML and start a standard with GEM/GLSL?  No  
time atm, sadly...otoh, a pd patch with the several shader objects,  
presets, and such would also be similar, although not human readable  
in the least bit...

...meso and vvvv!?!  Whatcha doin' slum-ing around here?  ;-)   
Seriously, I've always admired the screenshots and specs of vvvv, but  
never have had a machine to play around with it  :-( ...I'm strictly  
ppc/osx, tho I guess next year even that'll change....  'twould be  
nice if ya'll moved to opengl and went more cross platform :-)

l8r,
