I don't think Lansweeper needs to be doing SNMP scans - there is network monitoring software for that.
I would like to see the ability to request a SNMP GET of a specific OID though. I would like it to be like "Files" where it is up to the user to input the OID they want to do a GET from... ie. tblSnmpOids and admins's just enter the OID that has the data they want to get. A SNMP GET is then tried for every node lansweeper knows about using the given community string for that OID. It can then be stored and displayed like everything else.
SNMP and a method to add Static devices / IP's would be HUGE for lansweeper. As I said the admin can fig up the OID's they want to use, but the app needs a way to do this IMO.
