Hello Dan,
thanks for the feedback.

It should be a matter of overriding SpreadProxy.__request
and refactor SpreadTransport.wait_response to split out
the decoding logic (perhaps it will be better to put all
the message encoding/decoding stuff in a third, helper class
and subclass from this).

In this manner you should have a mechanism rather message-encoding
(XMLRPC, YAML, ???) agnostic; but since 0.3 I've added a
message checksum, embedded in an XML fragment like this
<requestChecksum>(sha code)</requestChecksum> at the end of the
XMLRPC message, so perhaps the best overall approach is still
to embed the YAML message in some sort of XML envelope,
to take advantage of metadata like <requestChcksum>.

Any comment will be appreciated, as usual.
