Let's not get hung up on this particular use-case. Let's just assume
people want to see (or even validate) whether a particular boost
component (library) builds against some other (externally managed) boost

If you don't like that use-case, here is another one:
A long time ago, Rene was working on a buildbot setup for boost. I
suggested that a plausible situation would be that contributors might
want to help testing boost, but not the entire thing, but only one
module at a time. They would have a known-good ('golden') build of boost
somewhere on their system, and a full build&test-cycle would then
consist in checking out the module, build it, test it, send back results
to the buildmaster. Quite a reasonably small chunk of work, we thought.

The whole idea was that this was fine-grained enough such that 1) more
people would be willing to contribute and 2) the time such a task would
take would be reasonably small, such that the official build / test
report would always reflect the current state (or with a very small delay).

At the time we discussed that, the test results posted were typically
between one and two weeks behind the state of the repository.

Do you find this use-case more acceptable ?
