Why? Why should Gunnar implement it in first place? Just open source the core, and somebody else will implement it for him.
thomas, is this sarcasm?

outta the suddden you postulate to open everything and start to playing devils advocate for the open source developers who out of their free will and with their own professional knowledge support gunnar and his core?
first thing is none ever said open source is healing all wounds. in our particular situation as community it is means to work together, contribute and preserve code in which companies may not have interest in. this doesnt neccesarily translate to hardware, even if id prefer it to be open as well, but have you ever seen me saying x1000 should be open sourced? however amiga hardware in fact becomes open thanks to private hacking, reverse engeneering, emulation and fpga projects.
now you also need to be pragmatic and justify expenses against contributions. this isnt even an option with os4 or the entities behind. however taking part in apollo irc i sense it helps a good deal to push apollo and aros forwards independently of each other. calculating interests, there might be some better, more satysgfying, more popular and cheaper future solutions for amiga fans than currently. software and hardware wise. and everybody needs to calculate his interests and investments himself. i do, certainly, as much with apollo, which i dont have btw, as with aros.
