I just tried out your progam (peeranha)... I like it... it's cool but can I make 2 suggestions:

1) Default TTL: you have it set to 20... most clients clip this @ 7... so this value is a little high and probably not even being used...

2) Sorting results/downloads/shares/etc... alot of times I look for my files based on size then connection speed etc... being able to sort by every column helps alot...

Just some thoughts I'm not a programmer so I have no idea how hard 2 is to implement but it would be nice to see ;-)
