Agreed that it would totally involve the BigTop community, and that that part
is up to them. You guys would know this way better than me, so thanks for
mentioning this issue Cos. I just kinda threw this out there but it's not a blocker
for me -- whatever makes sense here and it's a good point raised by Eli that 
can probably be solved a number of different (easily solvable and documentable) ways :)
