Cisco's NetCentral product used to do this by sending out a bunch of
SNMP get requests (for system.sysUpTime.0 as I recall)

However, this would best be done in a somewhat multi-threaded fashion.
You would send out a bunch of queries in parallel and handle responses
asynchronously.

A custom SNMP solution might be better for this.

FYI - I believe there are more sites that block SNMP than block ICMP
