This looks good.

Another question.

Has anybody an example client-server example of bert?

I'm thinking:

           server in erlang  = bert + mochiweb/misultin/cowboy/yaws ...
           client in browser = jquery + bert

Id like to make an ajax RPC from the client that returns a bert blob
unpacks the blob and displays the result.
