One could take a look how http://www.delphipraxis.net/ does it. The forum with the best usability I know.
O, NOOOOOOOOOO. I hope not.
delphipraxis.net uses vBulletin. I don't know if it's available but they do not even have a usable mobile-view.
Maybe the newer version of the forum-software on this forum has other options. I know they updated software has a better mobile-experience.
