Thanks for that, sh scripts have always been lots of fun for me, i will
try and update the wiki if i get a chance. i  did offer to do some OZ to
angstrom wiki stuff if i get the chance and there are a couple of
articles i would like to write for the oesf community (basic networking
and stuff, it comes up all the time)

is there any other scripts you might need, probely best to tell me now
so i can write them and put it on the wiki. one of the ones i have
sitting here is a script that stops mpd on suspend so that when you
start the thing again the music dosn't start blaring out which could be
a bad thing in a meeting or if you pulled the headphones out and then
turn it on (use to happen all the time)

i have one for acpid for use on laptops as well (kohjinsha)
