Maus - I agree. Staying LPI/LPD while remaining timely, responsive and reliable is a challenge in a flight-of-four scenario and starts to get much more interesting beyond that. Discussions that I have heard suggest that stealth operators so far are wary of committing to anything that tries to go outside the "red bubble".
Meanwhile, both the Russians and Chinese are working very hard on TDOA intercept systems that can also function as passive radar, while ERA - who made the Vera back in the WarPac days - is still very much alive, paying the bills with commercial ATC systems and improving its defense products.
As for Satcoms - it's been hard enough to do LPI/LPD, high-bandwidth, two-way satcoms on the B-2 so far...
