After posting this, I realized that I forgot to mention other projects that I visited recently:
The cyclos documentation and interface is really impressive. Like CClite, Cyclos has the concept of a ‘System’ account-type, which gets debited when credits are issued to members (at least that’s how I understand it and I could be wrong). The System account-type is very similar to an ‘unused revenue’ budget in the revised accounting system that I am working on.
However, in a cc-implementation, a System account is primarily used to track the total credits that could circulate or are circulating in a system and tends to be a static quantity that is dependent on the number of members and debit limits. In contrast, an unused revenue budget tracks how much credits an entity intends to receive from the market and is dynamically (a) increased whenever the total expense budgets is increased, or (b) decreased when inflows are received. The unused revenue budget is expected to reflect inventory or productive capacity rather than the number of members in an entity.
The other projects that I visited in the last weeks are opentransact, flowplace and the marketplace module for drupal. There are also many discussion groups, including agile-banking and ripple-users, with participation levels that are somewhat encouraging.
