Portscan != necessary, not entirely.

KDE project "Lisa" actually operates this way, to find
"non-co-operating" servers. However, NMB, NBP, Lisa servers will already
answer queries and provide pre-assembled "browse lists;" and SLP and DNS
WKS records can also be assembled for GNOME- / ZeroConf- compatible
systems. (This is already being done in Mac OS Jaguar = 10.2 coming out
in a few days. We could probably hijack some nice BSD-licensed code
within the next week or so :-) )

Ideally, just scan our domain's DNS for WKS records and possibly a
pre-configured LDAP server (for the "managed" networks, e.g. at a
corporate office), and broadcast SLP / mcDNS queries for the "zeroconf"
environment (especially laptops, handhelds, &c). We could also look for
a Lisa server, if one's around, but one big problem is establishing the
IP range to be scanned. (EG: My LAN uses the private-use
area... that might mean a portscan of 2**24 (+/-) possible addresses!)
