Currently, the Striders are actually doing just that - they tossed their credits to Dave, who takes care of most financial transactions as the "money-holder." It's slightly more complicated than just paying the rent individually, but it basically amounts to the same thing.

In that case, it seems like it functions pretty much identically to the current credit system and is different in name / "flavor" only. That's another thing I agree with Alba down there on - I actually am fond of the current way credits are dealt with on a setting basis too. There's also the idea that credits can be offered as a form of currency, it's just a lot more valuable than, say, a month's worth of salary.

Either way, though, I'm down with whatever is chosen like I mentioned on Plurk. These are just my thoughts on the issue! :V
