that's the bottom line, it seems ...

for external scans of my own network, then, the only option looks like
an external box with root privs.  likely a VPS would do the trick;
shame that that can't "somehow" be done from a shared host :-/

i suppose there's a way that i could build nmap onto a xen guest
instance inside my lan, but i'm not at all clear (yet) what the effect
of trying to nmap-scan my own network's external IPs from inside is
...

anyway, thans for clarifying -- and for the help.
