With so many flavours of distributions and backports with slightly different library names etc., or just with all those conflicting updates kicking in without prior notice, we just have to accept that it takes an awful lot of time and monitoring to curate all those packages.

I came to the conclusion that a) this is too much work for a spare time activity and b) that quite a lot of how to do it right is similar to how Debian/Ubuntu already works. The PPA concepts is something that Debian wants to have for quite some Google-summer-of-codes back and I completely agree that it fits well also with cran2deb.  What was missing when I last looked at cran2deb was an inter-distributional/inter-release specification of how build- and run-time-dependencies should be speficied. That added, and with a common server, there is little speaking against just working on the same code base, from what I oversee.

Many greetings
