Doesn't imply order though.
A rsc_order M:1 with score=0 will indeed achieve a bit of this - the
dependant resource will be started afterwards, if any of the resources
have started. But if there's several, it will only be started after all
of them have done so.
For {M1, M2, M3} -> N, the behaviour requested would be: M1 N M2 M3, for
example, if at least M1 has started.
What M:N constraints right now would give is {M1, M2}->N.
It's sort of like "interleave" with clones.

Lars
