I'm guessing there's a number of people whose approach to bitcoins is minimal: those without hardware for mining nor money for investing.
There is as well a number of ways out there to get small fractions of bitcoins which by themselves are useless.
I'm proposing a team of such low-level owners to gather fundings with the purpose of gambling them, so this fractions can be of some bigger use.
As for the specific, we should of course found some way to prevent anyone from this "party" to fuck up the others. I'm thinking of some web wallet with common user and psw? Trust is of course essential and I myself might back off from this if I don't get a good feeling from the proposers
