Simple, straight forward, but gives you total control.
I have been using older versions of Beyond Remote for a couple years and have never had a problem with it. Get it if you want complete control over another computer, just like you were sitting right in front of it.
Pros: Simple, you can figure it out on your own. You can loosen up graphic quality to make it faster. (I used this alot over dialup to fix out of state computer problems). Has security features. It is pretty much exactly how I would design a remote computer interface if I knew how to program.
Cons: I can't think of any.
