The cheese shop is seriously out of date, at least according to PIP:
$ pip search amfast
AmFast - Flash remoting framework. <snip>
INSTALLED: 0.5.2
LATEST: 0.5.2-r532
Browsing the source tree I see that r532 was committed on Oct 23, 2010, and that the latest repo version is r542.
Can the cheese shop be updated, or is it best to just download the source? PyPI+pip is just so darn convenient, though, especially with the automatic extension building.
