Actually, I kind of feel stupid for not knowing that. I'm a pretty geeky guy, but don't have much experience dealing with routers, wif-fi, nats, etc. LOL, for a second I thought LimeWire was masking users IPs in order to thwart the RIAA or MPAA.

I suppose I could always do a "netstat -n" and track down their address. When I find someone sharing good stuff I like to grab files over a period and not leech off 'um all at once.

Thanks for additional the info.
