Only problem is, once we start anything like a formal barter system, it comes under the IRS. The way to avoid that is to keep it a volunteer organisation with an expectation of time commitment to projects or to payment of membership dues. Not-for-profit organisations are of course regulated in a minimal way (think of your local Model Railroad Club), but the accounting isn't as strict and the membership transactions don't have to be reported in detail. -gg
