Right, portability plus extensibility.

Well, I'm not clear what additional code is involved? You need to do all
the (pre)processing anyway, so why not just serialise the results of
that processing as XML. That makes the information available not just to
the mobileOK Basic tests but also to some aspects of mobileOK (full) and
to other ad hoc tasks.

Agreed with that, but I guess as part of a decision making process. We
do need to come to a conclusion in a reasonably timely way. So, what do
we need to know and in how much detail do we need to know it?

Just to repeat dotMobi's invitation to discuss all this F2F in Dublin.
If we could assess willingness to attend, timescale and agenda, then I
think that would frame prototyping and other preparatory activities ...
