Andy,
I'm not sure what qualifies as a *good* example. A simple example
might be:
cs2cs +proj=utm +zone=11 +datum=WGS84 +to +proj +zone=12 +datum=WGS84

cs2cs +proj=utm +zone=11 +datum=NAD27 +to +proj=utm +zone=11 +datum=NAD83

This is not supported by PROJ. I see Oscar has provided excellent
details on how you could accomplish it.
