[BNM] Complementary currency systems

[Michael Bailey]

Hi All,
I've been doing some work for Home EcoVillage and I'm looking for an open
source, PHP complementary currency system somewhat like
Cyclos<http://project.cyclos.org>
 .

Cyclos <http://project.cyclos.org> is a Java based app with many server
requirements which would mean a hosting upgrade. I'm hoping for a PHP/MySQL
based soltution which won't incur a hosting upgrade cost.

Does such a thing exist?

Michael.
