I think, they are mostly dublicates, bug 145737 was the original multilib-portage idea of kanaka,
but he discontinued it. The version of today (bug 306835) does partly base on his work and partly on
the work with the native-multilib eclass from some Gentoo users with some additional changes from me.

Most communication is done in #gentoo-multilib-overlay on freenode IRC. I have also created a mail
alias (multilib@g.o), but it is only used for some bugzilla assignments at the moment.
