Right, this is not an argument that you should switch to AFS, rather, an 
argument that the design approach of persistent client-side caching first 
adopted in AFS isn't just about raw bandwidth or latency to the client, but 
about improving the ability of the server to scale to large numbers of 
clients.

All that said, I'm really pleased that Arla is working much beter on FreeBSD 
lately, and that significant work has gone into an OpenAFS port for 7.x and 
8.x.
