I would get involved in that, in my last company we did both forms of
replication i.e.
1) A record has changed, replicate the whole record (simple, easy to code,
heavy on NW traffic)
2) A record has changed, lets store thenew values to a role forward log and
replicate just the changed data. More complex to code, more tables required,
a bugger with Blobs.
We also produced a DB Comparer that would run periodically to ensure DB's
didn't get out of sync.
