Some of this functionality is probably exposed via hostapd. Here's a 
couple links with some background / more info:

https://w1.fi/hostapd/
https://help.ubuntu.com/community/WifiDocs/WirelessAccessPoint
https://wiki.archlinux.org/index.php/software_access_point
http://www.webupd8.org/2013/06/how-to-set-up-wireless-hotspot-access.html

If you decide hostapd does offer what you are looking for, it might be 
worth considering contacting the project directly with your intentions. 
Note, it's a user daemon, with some frontends. You could work on 
improving hostapd itself, or a frontend, or both. Perhaps you want it to 
be more easily used with NetworkManager for instance?

Can anyone speak more directly about hacking on linux wireless drivers 
in the kernel?
