802.11ac isn't out yet but I have little hope of it really helping. I live in an apartment building I can already see 50+ routers on 2.4 & 10+ ON 5GH.
I just don't see that much of a benefit unless the congestion avoidance is really better than 102.11n.
You are probably right. I think this invention will be of more help: http://hardware.slashdot.org/story/12/10/23/1946248/increasing-wireless-network-speed-by-1000-by-replacing-packets-with-algebra It works basically "repair data" in RAR archives for WiFi networks, so distorted/damaged packets can be recovered even if their checksums don't match.
