I was poking through the Time Synch thread, and it sort of got me wondering something else; in 40K, they don't seem to have hyperspatial communication. If you want to converse with someone any real distance away, say even from Scintilla to your ship out at Zayth, astropathic communication will be the only way. This will entail you having to formulate a message, give it to your AT, and have him start pinballing it off the heads of other astropaths, until it can eventually get to Scintilla, possibly to a specific astropath, or one employed by the public, depending, get decoded, be sent to the receiving party (not sure how that step is officially done, either), then they reply, and the message pinballs again, on and on. It just seems weird, if I accept it, that there is no "real-time communication". If one of your scouts picks up an opportunity, say he hears about the Dread Pearl auction, and thinks you might be interested, you can't talk to them, get info, clarify stuff, and then make a plan; there will be days of "waiting for the telegraph", and it seems surprising anything can get done.
How has this pack of communication affected your games? Did your players, maybe more familiar with Star Trek, Star Wars, or any other setting where transmissions can be burst-transmitted through Hyperspace/Subspace to allow face-to-face conversing have difficulty being effectively cut off from everything, or am I missing an aspect of grimdark astrotelepathy?
