The clubmask-oscar and the pbs-maui-oscar packages will probably need to be mutually exclusive chosen packages, we are in the process of working out that capability as well as other gui/installer changes and enhancements.
There may be other information that the user needs to configure for clubmask-bproc enabled nodes. This may be cluster-global in nature, in which case the clubmask-bproc package could have a configurater screen of it's own like any other package can, or will it need extra fields for each node that are distinctly configurable?

Oh -- the nodes are completely 'normal', just that they have the added ability to do bproc. The node is most definately separate, with a separate address ( ok -- lets just assume disk-full nodes here -- I haven't played with the disk-less case as much ). Clubmask allows the users to use either bpsh or ssh to start processes -- just that bpsh is much cleaner and faster. I guess I should have mentioned that the head node will also need this bproc kernel as well.

Cool -- thanks. I guess the main issue will be just me getting my butt in gear then, as the rest are easily solvable.
