I meant in their home directory. We actually trust people so much

space on the server so good citizenship is a must.

Right, which is why I'm not enthusiastic about letting people
install random things on machines I manage. If they want
something, and it's sane, I give it to them. If not, I explain
why and encourage them to try it on their own machines (or on
their laptops, which are less locked down).
As we're the math department, TeX is, of course, a must, and any
machine I build is going to have some nice TeX system on it.

Yes, our CS profs actually manage their own desktops, with
attendant hijinks. My faculty don't, except for the tiny number
of Windows users, who are mostly not supported by me. I'm pretty
sure that the CS folks only get to talk to their servers over
user-level connections, though (e.g., not NFS mounts). If the
Windows machines were more tied into our servers, I would probably
not let them have administrative rights on the Windows machines,
either. And if we were less dependent on NFS on the other
machines, I might be more open to giving them more control.

Yup. There's a balance point that you have to find that works for
your particular situation. For me, the ``extra'' work involved in
making sure people get the software they need installed is a small
price to pay compared to the possible problems that I might see if
the machines were less controlled.
The key, I think, is that we're a small enough department that I
can be pretty responsive about installing software people need
when they ask for it. In practice, that approach seems to be
working quite well for us.

Agreed, which is why I'm generally a fan of letting the
distributions do the packaging rather than having it done
upstream. The distro packagers know how their systems work, where
files are supposed to live, and how to get their packaging systems
to work. As they're all different (I'm a Debian developer and
also package a lot of software for our CentOS machines), it's
better for upstream to concentrate on the core software and not
worry about all the packaging stuff.
Windows, of course, is always the problem child, as there don't
seem to be many (any?) third-party packagers in that space.
