Just getting back to this, I find this reply slightly worrying. Firstly
it seems to conflict with the idea of "no backdoor access" for VO boxes
- when you say "to access whatever local combination of storage tech and
transfer tool exist" does this imply that you aren't just using the
standard SRM and gridftp interfaces? The whole point of having those
interfaces is that you shouldn't need any tweaking ...
Secondly, this seems to imply a large amount of time for someone to
set this up - are you really happy to do that at maybe 200 separate
sites, even if you do have access? And maintain it all when problems
occur? This seems to be more like a traditional model where people had
more-or-less direct access at a handful of major computer centres, each
with its own customised system.
