Everything you say is true. (Actually, I wrote a paper to this effect in
1994...)

Yes, for people who don't understand the difference, they need to realise
that it is "chalk and cheese" as we say here in Australia. HL7v3 is a real
advance, and a completely different animal from v2.x
For anybody wondering, GEHR is tracking the HL7v3 work and aims to
incorporate as many of its good ideas as possible. In the coming 12 months,
we foresee a number of clinical trials of software based on our work,
possibly others based on CEN, and presumably work based on HL7v3. And
possibly further work coming out of this OpenEMR effort. Plus CorbaMed....
I think anyone who dreams of a utopian architecture for EHR/EMRs (admit it -
we all do, at least a bit!) should expect to wait at least this long as each
of the above proves itself and works out its problems and benefits. The
result will be a refinement of information models, and I predict some amount
of convergence, which might mean that the Utopia is indeed attainable in the
next couple of years.
So ... I don't think people should expect to be able to agree the ultimate
architecture right now - that would be premature. What people should be
working on is good sets of requirements for EMRs, and trying to agree at that
level. And the other area people might want to get interested in is methods
of defining meta-models to drive concrete EMR models.
