I don't think [ssh tunnel would] be any easier to use and it really only would work for one user anyways (the advantage of sharing internet via wlan is that your friends can use it too)
Some rather smart people are trying to get the modules working on the stock kernel, and if it is impossible (it seems some "unused" symbols that these modules depend on are stripped...) I'll see if I can make the powers that be to see the light and maybe we'll have a new stock kernel...
In this case you only need to flash the kernel which will take less than 30seconds, of course it's a hurdle and a bit scary if you have never done it before. Flashing the stock kernel back is equally simple once you have extracted the kernel from the Fiasco (kernel+rootfs+whatever bundle) image so no need to lose any settings or data.
