limiting file size isn't really the answer, as ukbobby said, but I think limewire should intergrate with an anti virus to scan all shared files for a few reasons.

1. It could prevent the sharing of that file from the host (only on those running limewire, I know, but it's a start).

2. If those not running an anti-virus had limewire tell them they have infected files on their PC, maybe it will get them off their asses and get protected.

3. Many people who run anti-virus software still see file sharing as a great potential risk, and do not share / are deterred from file sharing because of this. If Limewire had virus security it could decrese the perceived threat.

4. What other file sharing app has this feature? I don't know of one anyway, except the windows live messenger sharing feature, which intergrates its own anti virus. Stay ahead of the game.
