Why isn't it just a "read only slave".  Do some systems
have read-only slave databases that can't serve as a warm
standby system as well as this one could?

Master/Slave Replication and Warm Standby systems are common
enough terms that I can google them or look them up in many
computer science books.

While coming up with creative politically correct euphemisms
might be fun, I hope we stick near terms that other DBAs could
already be familiar with.

ISTM the best way to refer to it formally would be a  "Read Only Slave / Warm Standby"
system, even if informally we might have informal
discussions of "just how hot our slaves are" when hot-standby
features get added down the road.
