We're about to wire our building with Ethernet coax.  Initially, about
half a dozen 3B2s and maybe ATT 6300s will be connected, but we expect
substantial growth in the future.  The problem I'm worrying about now
is how to plan for easy additions to the net, specifically adding
transceivers.

One solution, of course, is to use vampire taps.  But the Ethernet package
for a 3B2 includes a 3Com transceiver, which uses barrel connectors.
So we're contemplating putting connectors every 12.5 meters or thereabouts,
allowing for easy access.  (Total cable length will be about 300 meters,
comfortably within the spec.)  Is that likely to add too much noise?  All
of the wiring will be in the ceiling, which is moderately accessible.  If
we need to add a second transceiver in the same splice as an existing one,
we'll just add a 2.5 meter jumper cable between the two transceivers.
