Yes, but even if we build locally we _do_ still use NFS for the source 
tree and that is not something I expect to change. My "workstation" is a 
Solaris box, my build machine is whatever I'm targeting and I do not 
expect to have to transfer edits between my workstation and build 
machine (I've worked that way in the past when my workstation and build 
machine were on different continents, and I don't expect to have to do 
it when they are next to each other!)
