more softbody goodies:

SB collision targets may be picked up from modifier stack
works fine with static targets having subsurf and/or array mofifiers
see-->
http://www.wund.homepage.t-online.de/hidden/Mstack.blend
http://www.wund.homepage.t-online.de/hidden/Mstack_II.blend

however when calulating the SB object dynamics the vertices of the
'deform only' m-stack result are used

so SB <-> SB may look strange
subsuf modifier is applied to SB object after doing SB dynamics
(that is: colliding mesh is subsurfed, SB is not )
subsurfed SB cubes colliding

or may give unwanted results
subsuf and array modifier is applied to SB object after doing SB dynamics
link --> http://www.wund.homepage.t-online.de/hidden/ColSelfMod_nobug.blend

last, modifiers that change vertex locations in time (like waves)
suffer from not beeing seen at needed time resolution
(SBs see colliders static in a frame)
well but that's beyond the limits of the current dep-graph use
and needs to be resolved on design level

anyhoo have fun
