This slice is too big for me :( It is very interesting, indeed, but when you have full-day payed work, not related to FreeBSD, you have only very short time periods for such projects. And it is not type of project, which could be done when you have pauses at work -- it need access directly to hardware, and cannot be done remotely, as port maintaining could be done. -- // Black Lion AKA Lev Serebryakov <lev@serebryakov.spb.ru>
