Thanks for the explanation Michael - so ideally, the
Vary header that mod_gzip emits should be constructed
from the request headers it touches using these rules.

Forgive me if I've missed the point of the discussions,
but is this the general consensus so far?

I took the expedient way out last year by putting in the
Vary: AE header since most HTTP caches back then just
passed range requests through. Now, with Squid and
NetCache and others getting the ability to cache them,
I guess we need to be more precise about things.
