Josh,

I remember seeing an interesting talk at ICALEPCS last fall from a guy at
SPRING-8 that was using a power-over-Ethernet based in-house design to
measure temperatures. This wasn't an EPICS compliant system, but being Linux
based it probably could quite easily be modified for use with EPICS R3.14.
