The real question is: can eT have the compiler sufficiently ready in 9 months that you truly can recompile the app and release it with minimal tweaking? If they can, then there is nothing absurd about it. If they can't, then your strategy may have cost more but you've done the deed- assuming that you meet all the milestones yourselves, of course. I guess we'll know in 9 months. Until then, I agree we all should try to have fun. ;-)
"... They ne'er cared for us
yet: suffer us to famish, and their store-houses
crammed with grain; make edicts for usury, to
support usurers; repeal daily any wholesome act
established against the rich, and provide more
piercing statutes daily, to chain up and restrain
the poor. If the wars eat us not up, they will; and
there's all the love they bear us."
-- Shakespeare: Coriolanus, Act 1, scene 1
