I agree with Simon. That would be the only way to support
application-specified OF version.

But then I believe all apps would opt for OF1.0, because if an
application specifies its highest supported version as 1.2, it needs
to write the code to support different versions of OF. So, basically
the App would end-up implementing that complicated unified API.

Yes, it's really complicated :) On top of that some actions may have
different logics and that would be very difficult to unify.

It might be easier to force apps to use the highest OF version, and
writing a converter from say 1.3 to 1.2, 1.1, and 1.0. And throw up an
error, if there is an unsupported feature in the older version.

Thanks,
