Yes. But, you can always unplug the phone and replace it
(or, live without it) to get that drop operating again.

Well, that was the point. *Is* there ever a need (in a home
setting) for two drops in the same spot? I just couldn't come
up with a realistic scenario (aside from office) that would
The bandwidth requirements for video, etc. aren't high enough that
you would *need* more than one (unless you were an elecronics
store with lots of TVs on display :> ).
And, phone/audio is almost slow enough to run over a serial port...
I guess if you want to do lots of high speed transfers between
computers while watching TV on the same drop you lose a little...
(but it didn't seem like it would be enough to warrant the
extra effort of duplicate drops).

If we opt to reclaim the store room as "livable space" (it
is currently part of the garage), then I'll move the servers out
there and install a switch for them -- I don't see a need for
several drops to the main switch (since they are lightly loaded)

That's worth noting. My switch is currently mounted on a wall
in the "furnace closet" (?) so noise isn't as big an issue
as ensuring it stays cool. I *really* need to find a better
place for that but there aren't many out of the way places that
have power accessible and aren't going to be eye-sores...
Speaking of which, if I opt to do PoE, can I do that *outside* the
switch? Or, does the switch have to be able to accommodate it?
