Capacity is the maximum load that can be allocated to a node, and is used by
the XMLAssignmentMonitor to determine how much load has been sent to a node
(should be < capacity).
Different AssignmentMonitor implementations may interpret this property
differently, if
at all.

Each Job has a load associated with it, which, when used with the
XMLAssignmentMonitor
behaves to "cap" the amount of load on a node.

FYI above.

The interfaces are there to do so. I've always intended to contribute a:
GangliaAssignmentMonitor implements AssignmentMonitor{...}
GexecBatchMgr implements BatchMgr {...}
TorqueBatchMgr implements BatchMgr {...}
TorqueAssignmentMonitor implements AssignmentMonitor{...}
etc etc.
Some folks have looked at doing the above in their own mission specific
deployments,
but no one has done it in general yet. The Ganglia one seems to be the lowest
hanging fruit to me, and I already created a JIRA issue for it:

HTH!
Cheers,
Chris
