For Windows, I use the win-builder.r-project.org more and more. A really
useful tool.  Kudos to Uwe and Olaf for running this.

For OS X, a 'mac-builder.r-project.org' would be very helpful. Just this eve
I discussed OS X build issues ... without having any access to machine with
OS X.

For Linux, the admission to CRAN is a good test. And I dare say the cran2deb
autobuilder Charles and I are running also puts a decent test on things --
even more so that the usual CRAN test as we run builds in so-called pbuilder
chroot so that eg missing dependencies really pop up.

So: 2 up, 1 to go. Any volunteers for scripting OS X towards a builder service?
