Ah, at last, someone is thinking practically!
Yes, I think that's the way to go. The foundations have to be ported and made to use native APIs, FIRST. Most people don't realise all this 3rd party stuff that goes into things like Mozilla and OpenOffice - they should see what comes out when you try ./configure when building Mozilla on Linux. On linux you have to collect about 35MB of shared library tarballs if you want to compile Mozilla from source. Simply porting Mozilla or Openoffice by manually replacing all this by hand (the usual porting approach) would take years and the end-product wouldn't be maintainable.
