4.3 on the new Nexus 7 does not appear to pick up any ad-hoc networks out of the box.
Considering how quickly my N9's battery wipes when using wi-fi tether, I'm finding bluetooth tethering via BlueVPN in the play store to be a decent solution for now.
The main issues are that Google's applications aren't expecting an internet connection via bluetooth so you can't download applications from the play store or use some of their other apps; so for that reason I'm going to try to root and enable ad-hoc when I get a replacement device this coming week. But you can at least have some kind of tethering functionality through bluetooth in the meantime.
Nobody has released N9 infrastructure howto yet. I've compiled custom kernel with custom host-ap which in theory allows infrastructure mode, but I havent had time to test it as I'm quite busy with work.
Solved my own problem. Turned the wifi hotspot on android, and connected my N9 to it. Works great, but i would still like to do it the other way around. Why would android phone do it and N9 not?

Its atually of the question "Why android can only connect to infastrure mode and N9 can connect to both adhoc and infrastructure?"
As N9 supports connecting to both modes, then N9->Android hotsport works and other way around doesnt work by default (It only works if you install CM10.[12] custom rom to your Android, and after that your Android can also connect to both adhoc and infrastructure AP's.
