I would just like to place a vote for adding web2py to the official appliance list. I know you guys have a lot to do and I truely appreciate everything TKL has done. Just adding my 2 cents.
Since both Rik Goldman and Marrissimo (creator of web2py) have both submitted patches I would think (or hope) that would increase the priority a bit.
I am willing to wait. I currently use web2py but just manually installed on TKL-LAPP. Which works well enough as is.
I'm only voicing my interest in web2py and hoping for a official release sometime down the road. If not possible for this next release, then maybe the one after.
