Supposing you have more time for the Blizz-ABS Controller, would you consider adding the mouse? Well, just "adding" is something that even I could do, but what I mean is: moving at the mouse move (well, not that neccessary, and there are some scripts for that), clicking at the F5-chatbox, hotkeys and menu (the same - possible to do basing on existing scripts), and, what is beyond my scripting imagination, using mouse in the combat - at least as a target-select pointer (that would solve the online problem with the "Homing" and "Direct" skills and probably could change the AoE of Bow weapon category). But that would be an awesome plugin for Blizz-ABS itself, which I've heard you've retired from. So please call your padawans and tell them "hey, there's some n00b suggesting us making the Blizz-ABS looking like some outstanding WoW shit, go and slap him in the face 'cuz he's annoying... and start implementing that stuff if you can".
At the moment I'm working on a HUD and my game's skilltree database, but when I'm done I'll try to make an open-PVP plugin. Consisting not only open PVP on selected maps, which will be quite easy, but also "factions" of players and NPCs on those battlegrounds, which will probably beat me and my loosy Ruby scripting skills.
