How do I get 'dial-out' on demand?

Greetings,

I am seeking some suggestion as to how I can achieve dialout to my ISP
on demand.

My network is a Linux box (2.0.20) with 2 ethernet networks supporting
Win95 PCs.  The IP adresses on the conform to RFC 1597.

At the moment if a Win95 station wants to contact the ISP it has its
own modem (hence multiple phone connections) and as the ISP uses
dynamic addressing this causes problems with the PC trying to access
anything on the intranet whilst the default gateway on the PC looks at
the ISP.

What I want to do is to, instead of using DialUp Networking or Trumpet
on the PC to connect to the ISP, cause a process to be run on the
Linux box to dial up the ISP if there is not already a connection
established by another PC and then have the PC go through the Linux
box as a masquarading router.  I only want the dialup connection to
exist whilst an internal PC has need of it and if there is no PC
wanting Internet access at any given time then the dialup connection
is dropped.

Has anyone had a play with this idea.  Could I some how use inetd to
recognise that a PC on the network want to establish a connection?

All ideas are welcomed.
