well, I don't know how complex these programs are, but yeah,
complexity.. more code, more bugs, more time spent on tweaking
software, less fun ;)

heh, nice project :)

midish was designed for that

this will require some programming

I don't have hints for (1) and (2), I know neither ecasound nor

to record music last year, but the Linux port requires some

I think the discussion is OK, I'd just like to avoid "announcing"
aucat & friends before it's properly ported to Linux.
