The current version (0.11) is stable and is integrated with Cacti. The configuration variables are all adjustable through the console. It's processing my poller cache in a little less than half the time of cmd.php (21 seconds vs. 50) on a dual 700MHz. Not quite as nimble as cactid, but i haven't been able to get that to run a WMI query

Works with Cacti 0.8.4
It's being run on win2k, xp and 2003
Supports cmd.php/cactid functionality
SNMPv1/v2c support
Graph Exports
If you are interested in using it there is a readme.txt contained in the zip file that has installation instructions.
