I received the following answer of Eric Viara, EyeDB.org: "We planned to introduce soon a plugin mechanism to facilitate the way to write language bindings such as PHP5, Python, PERL and so on. But we do not know yet if the Python binding will be written by the core staff.
We do not plan to support XML in the few months. But as eyedb is an open source project, we expect that somebody else will write supports for XML." In any case I advised to him that the creation of a Google group would be positive to obtain a community interested in that project. -- http://mail.python.org/mailman/listinfo/python-list
