that's possible i suppose. but tyranids are the undisputed masters of genetic manipulation and could probably remove such hardwiring. although since the old ones are/were the undisputed masters of genetic manipulation amongst the milky way's native life (2nd only to tyranids), such hardwiring may be problematic.

i think it's a case of we'll have to wait and see what tyranids are like when they eventually win the war in octarius. it may already be that tyranids are prolonging the conflict because the volume of orkoid they've consumed is having the effect of making the tyranids there want to keep fighting :)
