heh .... sounds like your mom's a bit paranoid [img]i/expressions/face-icon-small-wink.gif[/img]

Basically, the ports that bittorrent uses, no other windows service does. If opening those ports on the router exposes something, it's exposing something that you've already got, and your network is already compromised. You're not going to get a virus from bittorrent ports, nor are you going to get hackers taking over your computer. It only effects the other computers on your network in that they won't be able to do much on those ports (in other words, only one of you will be good at torrenting stuff). Sounds like that's not a big deal anyway -- since it sounds like your fellow-users are a bit too paranoid to do that anyway [img]i/expressions/face-icon-small-wink.gif[/img].

As far as naming goes, the application name is more to remind you what it is. Linksys routers aren't smart enough to do high level packet filtering (at least without new firmware) -- all they do is point ports in odd places. If you were to log into the router in 3 weeks to set up a forward and you saw a service you didn't know the name of that was on some odd ports, you might not remember what it was unless it was appropriately named.
