Milestone, I humbly your suggestions will not help to answer the first question, unless you meant to imply ZERO revenue.
I humbly suggest that PDSG has generated nearly zero revenues, are projecting nearly zero revenues, and are grasping at the open source/cloud computing/SaaS as a last-gasp attempt to squeeze whatever they can out CDX.
They can take their expertise at data mapping, XML, ontology, etc. to all the conventions, workshops, open source consortiums, etc. they want at our expense .... but it ain't going to generate any meaningful revenue in the end.
Game over.
IMHO
