When target address is broadcast address...

good point, the above works only for SNMPv1 and v2c.
A SNMPv3 request message with a zero length engine id would trigger a 
report from all agents. So an easy way to do a "SNMPv3 agent discovery" 
could be to build such a magic message, send it out using an own socket 
and watch for the responses of which only the source-address is interesting.

Is there any tool out there, that does this already?
