I understood that they were going to offer V3 as an option (slightly
different to "migrate to V3")

we intend to have rather a lot of stuff. Both tools and run-time libraries 
for V2 and V3. Correction: That's what I intend. 

We've not discussed V2, but perhaps now is the time. I am busy porting
our V2 toolkits to Eclipse for OHF
- run-time library with validation
- message editor
- conformance profile editor + code generator
- metadata viewer

I think it can provide the right support - it should anyway. 
I will work on it a little more, then do a limited release to
any other ohf committers who are interested for evaluation
