At our meeting on the CUE Environment earlier this week, we discussed this
very issue. The consensus of the group was that we would in the first
early implementation go as planned, but once we have good tools in place
(rdist or other software distribution tool) that we could easily implement
distributing directories like /usr/local. We also realize we need to
look closely into compilers, license managers, and where to locate /opt.
Again, this may for performance reasons as well as licensing, be something
we want to distribute to locally attached disks.

We will definitely look into pine and in fact think we should down the
road pull together a small task force to consider mailers carefully.

This sounds like a good alternative. I think there are a few folks on
the site already using this. As I understand it, it may not provide the
full desktop capability that some users may want, however it might be
a very good alternative to provide.

Thanks for all your comments!
