Has anyone tried SNMP protocol yet?

Hi, I just found rebol has snmp protocol available - nice work, really, I did not expected it :-) I will probably try it at home with my Router, to see how it works :-) I just wanted to ask, looking at Google search for snmp protocol, that version 3 is already available - do you think snmp.r could be extended to support newer snmp protocol versions? Or do you think that it would have be completly redesigned? So basically - has anyone used snmp already? One other question - maybe it is not needed to support the latest version? Will snmp.r work even with devices supporting version 3 for e.g.? What will be the limitation? Just some features? Or will not it work at all? I do know little about snmp yet, so sorry if my question are rather stupid :-) Thanks a lot, -pekr-
