> I certainly know that it's doable, I'm more curious to know how much the two can differ (ULA, PD, PI, privacy, etc.). I'm looking into using two prefixes because of the privacy options ($WORK is health care, so some data is highly sensitive), but there may be other reasons to use two prefixes.

I believe I would just use privacy/temporary addresses by default, and
pull MAC<->L3 mappings off the switches/routers for the purposes of
auditing.  That way you're more likely to notice when someone changes
IP addresses (IPv6 or otherwise).
