Replication through WAL

Is there an easy way to read the WAL files generated by Postgres? I'm
looking into writting a replication deamon for postgres and think that
the WAL files are the best way to know what has happened to the db and
what has to be replicated. I have a roughed out idea of how to code it
up but the only thing I'm really wrestling with is how read the WAL
files. Can anyone give me some pointers. I've looked at all the xlog*
code and have a basic understading of how it works, but not a real good
one. Any help on this would be appreciated. Thanks

Many believe WAL will be the basis for further replication features.
We will discuss this as part of 7.2 development in a few weeks.

Not sure. I recommend hanging around, and when the discussion starts,
you can add things.
