Anyway, the important thing is, i think, to seperate the "pd engine" (or libpd) from the GUI part - indepedent of which Qt, OpenGl, Tcl ... GUI we might use in future ... and it's good to hear that there are some people interested in that ... :)
hm ... although i'm not really fan of cathedral building, maybe it would be a good idea to write down some kind of language specification and a list of requests. basically i'm thinking of splitting up pd's messaging and dsp core from the rest ... still thinking about how ... and what's part of pd's language and what of pd's library ...
