There are a few possible problems.  The first problem is that there are to
many nodes on that line as has already been mentioned.  There are other
potential problems though that I would like to hear from others about
such as: what happens when different kinds of cable are used between
nodes.  Is there a reflectance problem? 

 Also I would like to hear about
the problem of capacitance.  We have been using old localtalk line with
modular connectors and I am concerned that the shielding in the cable
increases the capacitance per foot above that of twisted pair cable.
