@ master, i'd agree with that with the exception that i think the hive mind must know of the webway - there are tyranid organisms that gain access to a victim's memories upon consumption of their brain, and every facet of information from every tyranid organism goes into the hive mind, as long as there's a single synapse-creature in range. given that many eldar have been eaten, as well as god knows how many other species/individuals who had knowledge of the webway, then the hive mind should know of the webway, it just wont consider it important right now.

getting there is another matter though: there's far too much biomass in realspace for tyranids to care about the relatively little biomass within the webway and commorragh... yet. also, since the webway is another dimension tyranids probably can't sense the biomass within it until/unless tyranids gain access themselves. i don't see tyranids actively trying to get into the webway, for the forseeable future at least, but there is the chance of them consuming an eldar world or craftworld which has an active webway portal, and then a few hundred-thousand tyranid organisms might well go and have a little look... :P

i just had a thought - i don't know about the construction materials of dark eldar or exodite eldar webway portals, but craftworld eldar use wraithbone for everything, including any webway portals they make. since wraithbone is a semi-organic technology then it's totally feasible that tyranids could make use of it. tyranids have completely consumed a few craftworlds and any webway portals on-board (and since craftworlds are made of wraithbone they can be completely consumed - iyanden got very lucky), and along with any knowledge siphoned from eldar minds it's not outside the realms of possibility that tyranids could potentially create webway-portal-bioforms. now that's a truly unsettling thought - they may never gain use of warp-travel but they could potentially gain use of webway-travel.
