What I would love would be to be able to have a sort of auxiliary HUD on a mini 8" or 10" monitor that could for example, track things like Vent servers, who is online, your average damage this session, total kills this session, honor gained this session, your latest arena results, etc. Pop up messages when things you need happen. A sort of sidekick feature that would automatically set itself up and automatically display at a glance data. Stuff that is important enough to know but not critical enough to go on the main UI. It would also be great if this information was aggregated across WoW's. This may or may not require an outside interface to allow the WoW sessions to talk together. I know the Bliz API is very limited about writing data although in theory, one could simply have an outside application aggregate/poll the data across a network and compile it in real time into a HUD display.

It would also be very neat if you could set up a small touchscreen display that would let you designate targets in milliseconds by simply clicking on their names in your touchscreen. So, mouse over their names and then click 1,2,3,4 and presto, you have loaded up 4 separate targets for your "alts" and then you have one for your main and bam - click once and 5x hexes or polys or what not go off. I don't think you would need IS for that but still. There are tons of VERY helpful ideas out there that could really help bring incremental increases in PvP/arena viability and I would love to finally see some people tackle them.

As a disclaimer: I don't know how much data one can pull out of WoW through the API. I think Bliz strongly limits the flow of data from applications to external files. It may not be possible to do the above without programs like IS or some kind of memory scanning program, which probably falls beyond what is legal under the TOS. I could see applications like the above being facilitated by IS and I think most people would argue that a aggregated data HUD would be useful and not the same as botting but still - I reiterate that this is a very fine line and until (if we ever) get clarification from Bliz, it seems like a good idea to ensure the community continues to maintain a reputation of being above board and not using programs or even offering up the belief that we are using special botting programs to give us an advantage in game. Boxing is legal because it gives players the same ability (less in my opinion) as 5 equally geared players. We as a community need to take great pains to keep it that way.
