i got my hands on the newest tyranid codex and it backs up a thought i had on the shadow in the warp: the thought being that the shadow in the warp stifles psychic abilities and as such it could stifle daemonic abilities within realspace.

'the fall of shadowbrink' details how tyranids over-run a world where grey knights are stationed keeping a warp-artifact dormant (they were unable to destroy it so they could only keep it dormant). tyranids come, everyone gets eaten, and the resultant bloodshed activates the artifact (the maelstrom cradle) unleashing a daemonic invasion.

at the head of the invasion are a greater daemon from each chaos god and these 4 were sort of a gang known as the quadrifold abomination (though i'm not sure how they all got along given certain chaos animosities). but they found that they couldn't harness their power from the warp because of the stifling from the shadow in the warp, and this stifling itself helped to close the warp rift created by the maelstrom cradle, which in turn destroyed the maelstrom cradle too.

i entertain the notion that for the races of 40k to, not just survive but actually defeat tyranids, then they need an unprecedented alliance, or at the very least a ceasefire between races until the tyranids are done. but i still think for them to be assured of such a victory they would have to have some degree of co-operation from the chaos gods: namely that the frontline grunts of the war would have to be daemons in order to completely prevent tyranids from gaining biomass from every killed enemy (such co-operation from the gods may not be too far-fetched since the gods must surely realise the threat tyranids pose to their very existence). but now i'm not sure if daemonic aid would be as fruitful as i once thought - they could still deny biomass but, unless contact between 'nids and chaos occurs near the likes of the maelstrom or eye of terror, then the shadow in the warp can potentially seal any temporary or small-scale warp-rifts, thus minimising the effect of incorporeal soldiers: it doesn't matter how many daemons are fighting if the warp-rift is sealed they all get dragged back to the warp :)
