i've used this for 7 months now now to deploy our software to our lab-machines. it took some time to learn in the beginning, but after that it worked like advertised. it makes live so much easier.

Tyaris Major: it doesn't delete stuff on the server-side so you can downgrade to any former state of your system. i am lucky as i didn't have problems with the portability so far... it works in our lab with 1 ibook g3, 1 ibook g4, 12 emacs g4, 9 (different) powermac g4 and 8 powermac g5.
