While installing software on the O2 is slow enough as it is, having some kind of quality-assurance from Gentoo/MIPS in the form of ACCEPT_KEYWORDS=3D"mips -~mips" would definitely make installing software on the O2 less painful. Believe me, I've been there. Compiling some package on a 300MHz R5000 takes hours, and then you find out that it's clearly _never_ been tested when it breaks your entire system so you've got to start the whole process over with a different version. I think the future of Linux/MIPS for regular users lies with Lemote/GDium hardware. (We're probably going to not worry about things like Octeon, for instance, since they're so expensive.) You'll notice that many MIPS kernel developer work for companies using MIPS in embedded environments though. SGI systems are cheap and available though, so I think we should make an effort to support them. The SGI Origin 300, with quad 600 MHz R14ks, 4 MB L2 cache each, and 4 GB RAM is quite a fast system. Unfortunately, the port has never been finished. O300s are quite cheap (< 300 USD) and would make excellent Linux/MIPS systems, if only the kernel port were completed. I hope I've answered your questions. Please let me know. Thanks, Matt
