OK. > ed0 serial > outside world <===> desktop machine <======> laptop > > My questions are: > > 1) Am I right in thinking that this is possible Yes, but why not buy an Ethernet card for the laptop and plug it straight into the network? :-) Is this an old laptop w/o PCCARD slots? 3c589 cards are ~$100 if you get them from the right place (but go fast -- the 3c574's will probably supplant them). If you can dial into the desktop already, it's a matter of running ppp on a different serial port and using a null modem cable between the laptop and desktop.
