Not just anyone can upgrade an ebuild file and con the gentoo world into updating. if you are wanting to know the "mechanism" of stable/unstable, it works like this: each ebuild (thats the "formula" that instructs the packaging system how to fetch, compile and install the package) has a keyword, which relates to the architecture. x86 means 'stable on intel x86', you can guess what sparc, ppc etc mean. ~x86 means unstable on x86 etc. if you set your environment variable ACCEPT_KEYWORDS to ~x86 then you can compile the latest unstable version of a package. Therefore you can run stable on some packages and unstable on others. On my system ACCEPT_KEYWORDS="~x86" emerge -up world tells me that if I upgraded to unstable it would upgrade 250 packages from my world file, and direct dependencies. There are moves to change to a three tier system like debian (stable/testing/unstable).
