Does that also include the case where client == server, and the "wire"

Yes.
So am I correct in thinking server side acceleration for old hardware
that
is very hard to make do DRI is a case of implementing acceleration in
the sever side mesa software renderer ? (a large case Im sure)
That sounds like the thing I had in mind. It looks to me like
stand-alone-Mesa (think back to the way things were around Red Hat Linux
6.2) already has HW-accelerated rendering for the 3Dfx VG. This ability
seems to me to have been removed (by removing the FX subdirectory), in
the version of Mesa in the DRI project. But correct me if I'm wrong ...
Correct.
I'm not sure I understand what you're saying.
I can't imagine a scenario where we would have hardware 3D
acceleration for server-side rendering, but not for client-side direct
rendering.
A long outstanding project is to allow the server to load and use the
DRI hardware drivers so that indirect rendering is hardware accelerated.
But what if there is no DRI hardware driver available ? Is it a sin to
try to find another way of getting HW-acc. ?
It's not a sin, but kind of weird.
And remember, I only see
this happening for the very old 3Dfx Voodoo Graphics card, because that
is (as far as I can see) the only piece of HW that Mesa has a driver for.
I understand what you want to do. I just don't think it's very practical.
