For kicks I spent a little bit of time thinking about what it would<br>
take to make Elephant work with BDB replication. There is one thing I<br>
don't understand, if a client wants to initiate a write transaction on<br>
the master, does it have to be a completely application level process<br>
(for example, you have the execute-transaction function call run<br>
remotely) or can you do this at a lower level where you somehow<br>
forward the low level read/write log information from client to server<br>
to be committed?<br>
