I've used Octopus for a couple years now. I'm very comfortable with it and best of all, it works with my Windows 7 64-Bit "Server" Machine and my other 32-bit Windows XP "client" machines without a hitch. (Minus the little UAC junk you have to do).

One thing I would like to see is a "quick" profile change setting. I have pretty unique keybinds which are centered around being able to play my other "boxed" toons on my main computer solo without changing a bunch of keybindings. I have one profile for "normal" boxing and another for "mounted" combat. It would be cool if I could hit a quickkey and change my profile instead of through the dropdown menu.
