About the kiddie Porn Thing..... You could possiblly give each IP a set amount of time lets say a day. You have 1 day to delete any accident files. I would Think That This would be hard to do but would make LimeWire Much Better.

And the virus checker would be some sort of minature virus software like a version of STINGER that scans file this would result in alot less frequent updates since i would only cover the more harmful viruses (Not all the little pissy one that pretty much do nothing)

Oh yer and can somthing be done about that only ony selection thing cause it would be great to have so users can vote twice.
