Mouse4 and Mouse5 - Solution...! Sort of.

Stardock Forums
I don't know why it duplicated my post when I replied to it.
Anyway, for those of you who want to use mouse4 and mouse5 on the secondary machine, you can do the following, which is what I ended up doing...
Look up the keyboard shortcut your browser uses for back and forward (alt+left and right arrow keys for Firefox), and use your mouse's software to set mouse4 and mouse5 to those keybindings. They will then be sent over to the secondary machine, since it's going through the keyboard... Or whatever. Then I just set my Warcraft keybindings to those key combinations and it works great.
