Enzo 2.0 has just been released to its new Google Code website. This release features preliminary support for inline Python analysis, using yt.
In the Enzo documentation there's a brief section on how to use yt for inline analysis. As it stands, many features are not fully functional, but things like phase plots, profiles, derived quantities and slices all work. This functionality is currently untested at large (> 128) processors, but for small runs -- particularly debugging runs! -- it works nicely. (Projections do not work yet, but they will.)
