I had CactiEZ running in a VM Ware on a Dell 1850 with 4GB of ram. It did fine with about 200 devices but the time would drift really bad. In 10 minutes the time would be off by hours. I am now running it on the same 1850 but not in a VM with a few hundred graphs now.

And would need a hell of a cacti box. But you could SNMP hit each customers CPE device if it supports it. That would be quite the load for the cacti box though. I second cacti easy though. We have a box running CactiEZ with 68 sensors on it, and it sits around all day doing nothing in terms of hardware usage. Every time I've tried it in a VM its had bad performance issues around 20 sensors.
