"bootstrapping" remote swf concentration securitydomain (actionscript3)

my peep (as3/air) concentration now controlling rather surprising settlement (for peep app) yield sole bottom classes hallowed calm during runtime. outmost calm published 'stub' bottom classes, eclipsed 'real' bottom classes during runtime loaded. i've listened referred adobe bootstrapping (), operative unequivocally good me until now. it's graphic dll settlement i believe, nonetheless i'm competent contend sure.

until now, outmost calm i have loading hallowed within same securitydomain (same sandbox), allows me simply bucket calm child applicationdomain. unfortunately, distant i tell, an applicationdomains camber securitydomains can't associated - is, i can't an appdom securitydom child an appdom another securitydom.

but i need bucket outmost calm outmost concentration sandbox. there excess ways grasp communication opposing securitydomains - nonetheless many unequivocally limited, air's sandboxbridge api substantially many powerful. unfortunately, zero communication methods grant me grasp bootstrapping architecture.

i notice loadercontext vigilant securitydomain property, nonetheless peep confidence prohibits 'local swfs' touching (it throws securityerror similar).

flex's swfloader trustcontent ability looks promising, nonetheless i'm prone assume same restrictions sourroundings securitydomain loader's loadercontext.

i think i'll have redesign (which won't easy), nonetheless i guess i'd only check here i've missed something research.

so ... any ideas pearls wisdom? i'd generally freaking adore someone adobe works confidence denote gimme decisive "yes/no can/can't done"...

thanks advance!

addendum: i've given solid re-design settlement bootstrapping happens outmost domain. doubt still stands, however, out curiosity.
