I remembered I had a meeting ... unfortunately I remembered the WRONG
meeting... apologies for being so slow to respond.
A few small things:

Somewhere there's recently been a discussion on whether a single WN should
still get a full green spot.
Certainly the aim at Brunel - assuming we ever get any nodes working at
all! - was that WNs would effectively come from a larger pool of machines
shared with other non-Grid users, with the allocation changing with
circumstance.
So wearing that hat I think functionality and volume of resources are
separate measures, and should be indicated as such. I was going to suggest
different sizes of spot - but the new map has this! Has someone beaten me
to this point? Either way the new map's page doesn't explain the meaning
of the spot sizes...
Security 1:
Owen (M) was taken aback when he came recently to find that at Brunel
we're trying to put the WNs on a private subnet, as we're NOT ALLOWED by
our CC to let them have have any IP connectivity.
I forgot to mention that part of this insistence relates to my point above
- at least for us the physical boxes may occasionally be running
Windows...
I'm not sure what the current state of play is as regards WN IP
connectivity, but it's not always clear to me that people discussing it
realise there are non-technical issues to overcome, too.
[I'm not saying whether I support or decry our current situation, merely
supplying food for thought]
Security 2:
Would Tripwire policies to cover the Grid stuff (especially the LCFG
server) be any *actual* use, and if so has anybody tried building some?
I made some a while back - see
http://www.brunel.ac.uk/~eesrjjn/grid/tripwire.txt
but I never figured out whether or not it's a worthwhile exercise.
(There's also the competence issue - I never managed to work out how to
get that version to simply do all the files in a specified directory,
making the list of certificates/CRLs a bugger to deal with...)
Thanks
