Thanks for the suggestions.  The network ferret tools reports to do layer 2 discovery as well, maybe not so wishful 
thinking but I could be wrong -

The best GPL tool that I've come across in a long while, as far 
as 
network discovery goes, would have to be the discovery engine 
inside 
Netdisco (http://www.netdisco.org).  This tool is fairly Cisco-
centric, 
but Max has put a lot of work into a tool for folks who are 
tired of 
CiscoWorks not working.

netdisco does automated topology discovery for CDP-speaking devices
(where the C is Cisco and not Cabletron).  That includes Cisco gear
and some HP stuff (at least the ProCurve line of switches - not sure
what else they have it in).  netdisco will also do topology discovery
using Bay's discovery protocol (though this probably only exists in
old stuff and likely didn't make the cut in the move to Nortel).  
There'ssome hope for using the work done by some guys at Bell Labs 
to do the L2 
topology discovery relying on existing MIBs (primarily the BRIDGE 
MIB),and there is proof-of-concept code, but that's mostly wishful 
thinkingat this point.
