OpenBox Mousebinds - Aero behavior
 

I've seen a million ways to configure OB to emulate Aero Snap via MoveResizeTo and such, but I'm curious how to do it with a mousebind. The actual functions/actions would basically be the same, with an added parameter to detect the window edge, such as "30 pixels past edge, perform this action." Is this function defined in OB, if not, can it be, and if so, how can this be done? I've scoured the OB website/wiki, the Arch wiki and forums, the #! forums, and the Archbang forums, and thus far, no luck. If it can be done via only OpenBox, all the better. Thanks!
