I wonder if it's worth the efforts.  Of course it's very nice to be able
to calculate the state of the system at several arbitrary points of time
but for most purposes this is not necessary since you either calculate a
complete animation or you just want one final result.  And your method
can't calculate any more complicated influences like wind, friction etc.  

BTW, you gain quite some speed advantage if you use a hardcoded system. 
If you turn off collisions between masses in Sim-POV and use method 2
environment
collisions you can use quite large time steps without problems and will
have quite negligible simulation times with particle counts like in your
sample.
