An AIX enthusiast i am and more knowledge is always good, it's just those
48h days no crazy physicist wants to come up with ;-)

Though not official, still very much appreciated! A machine would be no
problem at all, network access is a different story though, i'll have to
check with our security guys. My machines @home would be a last resort,
you'd hate me for my low bandwidth though ;-) Sponsoring could be a bit
complicated, since a) my lottery ticket didn't pan out - again ;-) and
b) we're in the public sector in germany, so lots of bureaucracy and our
procurement department is bound by some very "odd" rules. I'll talk to
my team leader and see what we can do.

Thanks for the pointers, i'll see if i can come up with some IOCP code.
If not i'll try the fallback you provided. I'll report back as soon as
Thanks again & best regards,
