Making OJ out of lemons?
As much as I love a) Debian/*buntu and b) rolling release distros, I remain skeptical of trying to beat Ubuntu alpha/beta repositories/Debian experimental/sid into a usable, stable-ish rolling release distro for the simple reason that, outside of Ubuntu post beta, their source of packages isn't really meant to be stable nor up-to-date with upstreams (and at times, it can even break "on purpose").
OpenSUSE got this right with Tumbleweed: it's mostly its own thing, outside the normal route/packaging chain for the non-rolling release. There was (is?) some interest in doing the same in Debian (or, somewhat more radical, changing sid into essentially a rolling distro), but so far it hasn't meshed well enough with enough Debian Developers...
