[ale] CIFS <-> NFS bridge?

[Dylan Northrup]

I don't believe it's an issue with packet sizes, et. al.  From the testing
I've done, the problem is the version of Linux we're using is a few years 
old and came out just before the fixes were put into place that would allow 
proper recognition of files that were on remote SMB mounts and were larger 
than 2G.  From my testing it appears this is strictly related to the linux 
version, not the version of samba (I installed the most recent version of 
samba and had the same problem, but testing on newer kernels, the issue is 
resolved).
