Case point - working on a massive multi million pound project that involves a lot of very hard graft, so far 2 months of man time has been used yet they have just scratched the surface, this is causing stress to a number of individuals yet with this software (I hope) it would take no longer than a week, in fact less. It's a dream, but it's something that could at least bring an AmigaOne into this office...
I'm sorry to be brutally honest, but you would have to be *nuts* to put in a platform that has one poorly-supported OS on it (Linux PPC - ask any Linux PPC user), and the other that barely has any software designed for it which hasn't even been released yet, for a "multi-million pound project".
For starters, any IT guys involved in the project would simply laugh you out of the office and you wouldn't be consulted again, but what about the main question, what assurance do you have that this new platform would work for your needs? Other hardware platforms are in far wider user already and developer support for them are much stronger as is general industry support.
It's all a very nice idea, and a "multi million pound project" that successfully used AmigaOnes/OS4 would do wonders for the effort of PR for AmigaOne/OS4, and I would love to read on slashdot about such a project's documented success, but no. Start small. If we could get all current Amiga systems in business use upgraded to A1/OS4 and articles written about them working perfectly and much better than the old systems, that would be the sort of thing that could start a good A1/OS4 advertising campaign.
