Matt,
The market is full of top-notch tools for solving this problem. From Acroni
s on the desktop market to Availl for server-server WAN synching. I'd see a
small market for appliances that perform this same feat.
Nobody really does block-level cross platform well due to differences in blo
ck sizes, filesystem formats, etc. After all, mapping UNIX permissions to N
TFS and vice versa is never a pretty feat...now try to get the diffs between
two separate block sizes on top of it! Tack on a live Oracle DB or somethi
ng else and you have even more problems to adequately address the Enterprise
market.
What somebody needs is a leased option for licensing to my clients!  Matt
, if you could write it, lease the SW for under $1,500/server/year with upda
tes and have solid, cross-platform code you'd have a market...at least with
us.
