In particular, I don't like the webserver being in the tree
but since we don't have a model for constructing RTEMS add
on packages that contain their own configurery, it is the
best place to ensure that it is maintained and gets built 
on a regular basis.

In general, they change so infrequently that packaging them
completely separately wouldn't be the worst idea.  Ralf is 
probably the best one to answer but we should be able to use
some CVS magic to reuse RTEMS configurery with separate pieces.

Some of these may be able to be broken out but as a practical matter
won't this make linking applications more difficult?

On the face of it, I don't really care one way or the other except 
for balancing complexity and convenience.  But it is a big change
from a user perspective and could have a lot of impact on build
Is it worth it?

And the goal of cpukit is to let all BSPs live outside the tree of RTEMS
