Sure, that's what the Trac plugin would do.

The biggest downside of that idea is that it would be very expensive
in SVN resources to ever give real-time feedback from testing, because
you'd need a separate checkin for each build step.

Sure it could.

So you *are* actually advocating a separate file in SVN for each test?
I guess I also worry about the performance cost of doing a checkin for
each test.

Unless we entirely drop our display distinctions and markup, or we
stick with the same fragile/unreliable display tools we have,
*someone* has to write new display tools. There just aren't any
existing tools out there that do what we want.

Unless Kitware is prepared to accomodate our display requirements, I
don't know where those tools are going to come from other than from
within Boost.
