Hi Nikolai, Basically what you're talking about is just happened - some hours ago 'ipset' was accepted to unstable, see http://packages.qa.debian.org/i/ipset.html When credits for preparing standalone 'ipset' package goes to Neutron Soutmun, yours truly played a key role in coordinating and preparing a non-colflicting upload of both packages (ipset and xtables-addons). Next challenge would be to backport ipset... Regards, Dmitry.
