Umm.. LAN adaptors ?  Yeah, that's the ticket -- BNC on the end of 
the modem to hack ethernet bridging, and leave the EIA-232 for control
signals, what about that ?  Given that PC ethernet cards only cost
of the order of $100 nowadays, it can't be that expensive to put
the same electronics into a modem, surely?

(For the rabid andi-bridgers:  I mightn't actually have anything other
than just a router connected on the ethernet with a modem on it,
ie:
	          ethernet        ethernet
	officenet<-------->router<-------->modem-->PSTN

Of course, if the router is smart enough, it could have n modems on the
end, and dial up only as many as it needs :-)

In which case of course, I say shoot the marketing men who sell
modems by touting 4:1 :-)  Thank goodness for more technical
forums like this.  Better make sure that the marketroids don't know
you're here, Toby :-)

But I bet that if I were NFS'ing mostly-zero-block databases across
that diagram above, a lot of the zero blocks will compress really well :-)
