i like the idea. like tournament of champions on jeopardy (no pun intended, lawl). would the AB be OHC format, or how long would the participants have to make their entry?
OHC format might be problematic, as you'd unavoidably have some people not be able to do it (or even not be able to be contacted)... maybe contact 8 people, and assume some attrition?
we might want to somehow make it more fair across any time zone, possibly similar to the Detroit/AA format, where each participant has a "GO" button and then gets 3 hours (or something) asynchronously. but in this case, entries would not even be posted for download/listen until vote time, to make the playing field 100% level.
also, what to do about packs for battle types that need them? would one of the users be nominated to provide the pack? or perhaps randomly pick a pack from an old OHC? or even randomly pick a module from modarchive/set of sounds from teh webz ;)
if you just wanted to do this OHC style, we could mostly do it right now. grassroots style (irc/msg board) for herding the participants, and the only coding that would be really key would be a "show me random OHC" button with an option to select format. (and i suppose adding the "legendary OHC" feature... maybe costs moar boons to begast?)
