I am wanting to block outgoing connections for certain apps, like limewire, bittorrent etc.

Would be good if i could do this on an application basis.

I would like it if this could be done without the user knowing to stop employees using such applications.

Can the built in firewall do this or do i need antoher application?

Little Snitch looks pretty good, but don't know if you can just set up the rules and not have it alert you with a pop-up each time?!

Any other suggestions?

Thanks

Here is another product to review:

Supposedly, the Mac firewall can be configured through Terminal to do what you want. The firewall uses the Unix ipfw program and rules can be set up in a file. I'm not fluent on those. I suggest doing a Google on ipfw rules

Why don't you just hardware firewall at the internet connection?

Why not just don't install one of the three evil P's (peer to peer file sharing)? Then you won't have to worry about it

jeez just install little snitch and save yourself the trouble...
