Some people who have routers don't want others hogging the connection, and some people don't want to lag when they're playing games while downloading photos from friends. I would appreciate it if mIRC itself would have its own limitter for speeds, rather than having to use an external program to deal with it, because it's quite pointless to waste system resources (my slow computer needs every bit of it) to limit overall download speed when you're just using mIRC.
