I would love to have them.
More or less everything is prepared, "only" issue is that nobody does 
something about them (yes, I should write a blog entry or something).
We have a cmake dashboard, we have scripts to drive the builds of kdelibs, 
kdesupport and kdepimlibs in svn, adding them for more should be trivial.

What we need is a machine which does the build(s), and, a person who maintains 
this machine and cares that the builds are always working (i.e. updates Qt 
when necessary etc.).
I don't have the time to do that.
