Dang... if only I knew C... I guess I'll just try the UML stuff next week
when I get the chance and see if I can make something work. I definatly
think this would be a handy tool for those testing throttle control so i'll
make sure and post it somewhere where people can get it.
While I'm at it... when I have that UML stuff installed properly and all.
Would it be too difficult compiling a new version of perl with a bunch of
modules like the current perl5 lrp? I wouldn't think it'd be too tough...
anybody had any chance at looking into that because if not I might as well
do it since i'll have to use it anywho. If anybody has any comments on any
of this feel free ;)
