Hi Sylvain,
>Since you will probably use remote view with a different back end, you won't need to modify your REPLACE lines because, AFAIK, you can still use them with remote views.

Exactly! I use views (local and remote) for updates based on user input and therefore use REPLACE. (No locking issues and performance should be better.) Whenever I do an update against a table, THEN I use UPDATE.
