I pulled apart a Micro/Mini/whatever EN/SC and a 2300 and the only place 
I could find inside to place the EN/SC's PCB was over the HD. When using 
a 9.5mm drive there is plenty of space.

On a 2300 the internal scsi port should be free for use, so I figured 
it's really just a matter of hacking a scsi ribbon. A low-profile RJ45 
jack can be added to a non-modem power card and there you have it.

However, at about the same time I was exploring this idea I came across a 
NetDock, that acquisition kinda took the wind out of these sails. :-)

The Duo modem is like a WinModem, partly (largely?) in SW, plus if you've 
ever looked at a modem 'card' inside a dock, it looks suspiciously like 
the same part inside the Duo itself. I don't actually know the answer to 
the 'will the dock modem work without the Duo's modem card being 
installed?' question but I'd say one cannot tell without actual testing.
