multiple particle groups for flocking

Greetings!

Initially I would like to thank you for the great sharing of the locust plugin - it really helped me a lot so far.

I would like to know some things though before I proceed with my project. Is it possible to create another bunch (group) of particles (in the same environment) that is combined to the central locust brain, so as the 2 groups move independantly to each other? - and this brings me to my second question which is "can these 2 groups somehow interact afterwards? (be aligned together or coherent probably?)" 

if it is not directly possible through locust can it be combined with other physics packages (e.g. kangaroo etc)?

Thank you in advance! I hope to hear from you soon!

Cheers,
