Yeah, I think they cost about 5000 Euro :) (probably a little less, but
around that figure)

True.
I'm not really a HW man, but I thought FPGAs were cool, because you
can alter the circuitry at any point in time, through some
interface. But probably it is best to fix the processor,
and just have some EEPROM that is flashable so you can just
alter the firmware afterwards.

*nod*
Only Open Source hardware is somehow limited,
it would be cool to have easily reprogrammable
DSP devices to do al sorts of kinky audio stuff :)

Hm, I'm having a course in compiler implementation next semester :))
But don't know if I would be ready to write a fullblown compiler
then yet. On the other hand, I can try :)

Sure, after the exams (argh, I should be studying now ;),
we could get together. I'm also a member of cwlab,
so I can get you an account on those machines (they have
public IPs so are ideal for 'worlwide' projects),
you can setup a site there (in the .linux.student.kuleuven.ac.be domain),
have cvs, ssh, ... everything is provided :)
I can try to get more people who have already had embedded system
design or who like to program in assembly for breakfast to
join the project ;)
Once we have set up a mailinglist / webpage / insert something,
we can take this offlist.
But for the moment it doesn't hurt I think, maybe we can
get some more people to co-operate that way.
I will be going to FOSDEM in Brussels too, maybe
there will be some audio freaks there too,
I will ask it on the fosdem-mailinglist.
best regards,
vini
