We've toyed with the idea, but
- last time I looked, I couldn't find sufficiently idiot-proof
instructions on how to add a specific VO to a site
(not for my level of idiocy!)
- there isn't a good way to find what possible VOs exist:

I'm not even sure offhand what "gridpp VOs" exist apart from
babar.
- Out of possible VOs, I wouldn't pretend to know whether we're
allowed to support ones whose members agreed to conditions of
use other than the LCG ones.
While that's mostly an internal issue here, it has to be taken
into account by any solution to the point above.
Incidentally, I think it was you that wrote in another post (which I've
deleted) something like "It shouldn't be up to Atlas to chase sites to
support them, (especially if they don't really need them)", though in a
slightly different context.
I agree, but with the proviso that LHC VOs on LCG are a special case.
In general the punters are being told that VOs are informal groupings
facilitating individual projects (which rarely last ~20 years!) - "
... dynamic, multi-institutional virtual organizations" says Anatomy of
the Grid - so that's likely the end up being how they try to use the Grid.
In that case, I would say that - in general - it IS up to VOs to go to
the sites to ask for resources. We're just fortunate that LCG is acting as
a matchmaker for certain VOs and sites.
But spare CPUs aren't really my problem right now... :(
