It should be considered a design critera of the *framework*, but not
necessarily of any particular module/plugin in the framework.

The framework itself is mainly a collection of infrastructure pieces and
APIs.

One can have HPC implementations of plugins and HA implementations of the
plugins.  Some plugins may work equally well for both HA and HPC clusters.

The interesting questions for the framework come down to these:

	Can a reasonable HA implementation of API "x" be created?

	Can a reasonable HPC implementation of API "x" be created?

	Does the framework cover every interesting HPC API?

	Does the framework cover every interesting HA API?

If the answer to these is "yes" for every interesting API, then the
framework is a success.

This is not to say that by day "X" that you will have everything you need in
the framework.  But, if you participate in its creation, and write some
components, then you stand a much better chance of getting it by the date
you need it ;-)
