As I have been saying for some time now :-( I will be having a new version coming out. (promises... Promises... :-) It has some additional flexibility in terms of scheduling. There is a load balancer and a directory shadowing utility (which I worked on in a paradise on the south of France -- Thanks Mike!) I hope 1.9.03 is reasonable as a release date--I should have support for FreeBSD 4.7 4.8 and 5.0 5.1 In the moment there are no plans for NetBSD. If there is interest somebody speak up--but since this is a FreeBSD list there probably isn't any. The short answer is two create two resources. As I recall correctly that as the schedule starts to find nodes to assign the resources to it will look at already running resources and calculate their mass on the machine and choose the machine with the least mass (or usage--sorry in a physics rut!) to assign the 2nd resource. VERY IMPORTANT-- you must assign a weight to the resource--otherwise all things will look equal and both resources will start on the same node. Hope this helps.
