Sheesh, why did I unignore you...
1. Not having a proper MUI re-implementation would affect Amiga compatibility in a very negative way (as it already does), making it more difficult to develop- or port applications for all 4 platforms, instead of easier (which seems to be the spirit of this bounty). MUI is the common denominator.
No it is not, stop fooling yourself (and others). MUI _could_ be common denominator, but with its current licensing, that is just not possible.
2. Since time and effort has to be spent on development *anyways*, why not spend it towards making it easier to port Amiga, MorphOS and OS4 applications to AROS
Why not break free from the legacy and legal nonsense that *anyways* hinders MorphOS and OS4 from ever becoming interesting outside inner circles? Seriously, why on earth let closed, narrow minded and retro focused projects dictate what a free and open source operating system is to become?! I'm not an "Amiga developer", but I was, I'd develop for AROS and screw the rest. AROS is _the only_ chance this... "plattform", has. Both MorphOS, with all its brilliance and yadida, and OS4, have locked themselves up in corners from where there is no escape. The only way to really survive is to give up legacy compatibility. The sooner the better! Geh, I'm repeating what I wrote more than a decade ago already... wtf am I doing here anyways. :roflmao:
