I've used the SNMP modules on a large project where I used SNMP to talk with different types of network equipment. The largest problem I encountered was not with the module but with the inconsistancy of the SNMP MIBs or rather how those MIBs were populated with data. There really needs to be a standard that everyone follows. /rant but what sort of road block have you encountered specificly, I might be able to help if I know what problems you are having.
