If you actually get to the fast computer over the internet (ssh or something) and build something off an NFS mount from your local machine, then there's a good chance that the latency in reading and writing files on the NFS share will far outweigh the faster processor on the remote machine, in which case you'll be better off building from your local machine, even if it is slower. (disclaimer: i don't know what kind of connection you have to the internet).
AFS is quite good in this regard, in that it transparently maintains a file cache on the local machine. If files don't change, they aren't re-read from the main server. Changes are sync'ed back transparently as well.
I have used this very effectively in a work environment. Chris -- fedora-devel-list mailing list fedora-devel-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/fedora-devel-list
