Angel tell me about your hacker skills, nice meet you. Your nickname is funny. =)
He just tends to exagerate :)
As you can see with some of my packages [http://aur.archlinux.org/packages.php?SeB=m&K=ornitorrincos] I'm interested in packaging for arch some developer tools(as NetBSD's make and the TenDRA C compiler, svn at the moment as the latest "stable" release is from 1998 but I wouldn't mind try to package it if somebody wants it), of course, I'd be interested in packaging some more C/C++ compilers(which are not gcc, variety is a good thing), I'm also interested in python, EDA software and 3d apps. If possible I also plan to package some GPGPU software.
When I saw your packages, the only thing I saw was the $pkgdir, $srcdir, variables to be used. But, Stefan wrote about that before, so... Some time ago i read about this GPGPU project. I don't remember if is the same, but the ideia is right. The GPU's can have a lot of processing power than normal CPU's. But, we'll need rebuild the actual arch's to do it...
porting arch would be something impossible as GPU's need to be programmed specially(more like the Cell for example than an actual x86 CPU) using Stream computing, I just plan to package if I can libraries and maybe some app
