It looks like the RPC widget should do most of what you want (could be
extended to fully support this concept), but it needs to be documented
and is not being used in places where it seems like it should. It
really shouldn't be too hard to put together a widget that does what
you are looking for.
I think isaac is correct on this point. The problem is that it is so
easy to put together case-by-case solutions for this that no one has
taken the extra time for a generalized one.
