Due to some temporary relocation of my ham shack for a home refurbish, I am
using my KPA500 remotely with the KPA500 remote software server running on
a spare netbook near the amp, and the client running on a computer near the
rig. There is one 100 ft long RG214 Coax between the KPA500 and the rig for
RF and one 100 ft small coax with RCA connectors between them for PTT. The
amp and autotuner are at the antenna feed and grounded well. The rig away
on the other side of the house not so well RF grounded, but there is no RFI
so far. That enables me to see the KPA500 status and change the band on the
PC in the shack. They don't yet seem to have the remote software for the
KPA1500 yet, but it is supposed to be coming.

I would probably accept visible conduit to run power if you can't run it in
the walls. As part of the refurbish, drywall was taken out and replaced and
the texture matched so new plumbing and electrical could go in.  They also
replaced insulation. That worked out well, but it was expensive. There is
not really any such thing as can't if you have deep enough pockets!
