Excellent. Thank you!!

EDF and DDF look perfect for putting the records into storage.

What about an XML based two-way stream (ignoring SOAP etc.. since it is
already a totally dedicated channel) and putting the actual channel data in
a kind of escape. I would leave it binary even if that isn't purely XML
compatible. EDF or DDF should be OK for the binary data format.

The reason for putting the EDF inside the XML as opposed to the other way
around is that the first protocol processor could easily separate out the
streams (control, data etc.) and pass it to the correct modules.

Comments?
