Umm.. so what? My 3 year old desktop got 300 gig. Server sytems should have
an access to even larger resources.

Anyway. The disk usage issue is manageble on Make system level. During
testing if library X depends on library A:N1 make system pulls branch N1
from snv if one is not present.Once library X testing is completed all
non-HEAD branches of libraries X depends on are removed. It will add some
time to the testing, but it can be optional and turned on in test host

Another direction is minimize amount to space used by temporary files. If we
move toward keeping test results in DB like external host. All files
produced during testing can be removed.

Do you know any tools that allows this kind of automated testing? This is
"nice to have", but not showstopper IMO.

Boost.Test now supports testing with shared libs on all platforms. I can't
say about other libs. As for "release variant" testing, I don't see what
stoppes each developer from adding appropriate test modules to the test
