If you can query host configurations you can at least get hints. IIS can
detect machines with modem/RAS DRIVERS (as opposed to actual modems)
loaded, so you at least know to look at the machine. Unix would be a bit
harder I guess as every unix machine probably has a copy of pppd.

If the machine is actually routing traffic off the LAN you'd be able to
detect it as a router if you can sniff the network, but other LAN
machines would need to be forwarding traffic to it.
