This is definitely the way to do it. We run fsl on a cluster of 356
dual-node AMD Opterons and have all user information stored in an
LDAP DB against which all login nodes and client nodes authenticate.
In an environment such as this and yours this is best way to do it.
As for xp you could set up domains in samba, have it authenticate
against the ldap db and use the same username and passwords to login
to both the unix and windows machines. It is a lot more complicated
that that but it is doable. If you go down this route I recommend
that you integrate the samba schema into your ldap db from the
outset, it simplifies things greatly.

I think as long as all clients and servers share the same password db
the nfs servers should only need to export your filesystems as r/w so
you can both read and write data. Of course your clients will need to
mount the exported f/s as r/w.
