I just had one of those wierd, highly impractical, yet exciting ideas that would be great if they could just be done. :-D
What if someone were to write an application that would take source code for a certain platform and, well, roughly port it to a different platform? Would not such a beasty save an awful lot of work?
Of course we'd need at least four of them: Windows to Amiga; Mac to Amiga; Linux to Amiga; and Unix to Amiga. ;-)
(I'm thinking of AmigaOS and MorphOS as somewhat similar here)
