Yeah, this is the alternative. We're likely to go this way as it's by
far the easiest to implement.
However until recently the app was consuming quite a lot of memory
under stress. While I think we have managed to get this under control
now, it still means multiple invocations of the JVM, etc... With
several instances, we're looking at having to add more RAM to the
servers.
Still it was interesting to see if anyone has tried (mis)using EOF in
this way...

Depends how many databases you have and how much hardware you can
throw at it, I guess...

We are evaluating this possibility. We have several identical
databases which we'd hope to update using WebServices through a
single WO app. All EOs have the same business logic. This app would
ideally choose the right data source depending on the login info. As
far as I can tell this is only possible if the none of the EO share
the same entity name.
