Why can we not have both? The 'cleaned up PLASTIC' *ought* to take a lot less time and could be agreed before Sept. In parallel and carrying on from that, some more formal and extensive messaging framework could be worked on. As long as all apps developers know that the new std will replace and make obsolete the old one with no guarantee of backwards compatibility then there should be no problem.
The longer this debate continues, the more likely that Plastic will become a de facto std like cone search: and that will definitely happen if we try to formulate a complete messaging framework from the off. It would be better if the IVOA had a hand in the 'cleaned up PLASTIC' though.
Or, we could simply accept that PLASTIC *is* the de facto IVOA app-interop standard and leave it to the people using and defining that to develop the 'cleaned up PLASTIC' standard.
