Maybe you can, but most people are using PBS and I'd guess it would be
pretty hard to get that to cope.

My point is that if you have any writeable space mounted across all the
WNs (especially home directories) you would get interference between
jobs for different users running under the same account.

At the moment the system usually uses scp to push files back from the WN
to the CE, and may allow ssh between WNs for MPI jobs, none of which
would work if the same accounts on different nodes belong to different
users.
