I don't know if they could be accessed without HTTP (eg by NFS), but
even if they can it's network traffic (not to mention the problems
of dealing with any NFS problems gracefully from a web POV).

We're also dealing with more than one validator.  validator.w3.org
is at MIT; qa-dev.w3.org at Keio, and I'm of course concerned
with valet.webthing.com in the UK - which has a much faster validator
than the W3C one but no privileged connectivity to w3.org,
making the issue of local copies more critical!

OK.  Round tuits permitting, I may well hack something up for this.
