Does that also include the case where client == server, and the "wire" 
is localhost-to-localhost ?

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 ...

But what if there is no DRI hardware driver available ? Is it a sin to 
try to find another way of getting HW-acc. ? 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.
