Amphora does look very cool. However, I am finding that installing it on e-smith is a non-trivial task. At least for me. The thing with Amphora is that it requires Postgresql and Zope. Also, to get the version of Zope running that they recommend you have to compile it, so that requires installing the dev-tools (kernel headers, gcc, etc.) That, in and of itself, is not so bad. I actually got Postgresql and Zope up and running with not *too* much trouble, but unfortunately, I hit a road block with accessing the Amphora page.
In any case, I agree that Amphora has potential but it is not necessarily an easy solution.
