You can do this currently without the WS enhancements, but you have to think
it through. The basic system is this:

1. Client side starts a transaction and changes the datababase
2. Client contacts server via a web service
3. Server initiates a transaction and makes changes to its database

To work, the condition then goes
a) Server succeeds and sends back a success and the client commits
b) Server sends back a failure and the client rolls back

The only thing missing here is the dual commit (ie, the server succeeds, but
the client cannot commit). As the client has already put the information,
wrapped in a transaction, in the database (provisionally), that should not
happen. The commit failing would only likely happen in a catestrophic failure.

Now, there are better modes for the long run, but you can institute this
today.
