Thank you!

I'll keep this in mind, I shouldn't need to do such large transfers 
again.  I'm taking one machine and splitting up duties.  I had to transfer 
everything to the second machine and then start pruning off things.  It 
should have been easier this way then picking and choosing a bunch of 
smaller transfers.

Next I need to get better at sharing disks and tape drives.  Every machine 
I'm working with is it's own little universe.  This has pluses and 
minuses.  Setting up the NFS mount the other night did end up being helpful.

I wouldn't mind having some of the Sun Netra X1s for web servers, but I 
need to come up with a backup solution since there is no way of sticking a 
tape drive in there.
