Yes. Except if you need something bigger than a toy, I suggest you look at
the python-gobject bindings. Vala generates gobject-based api which complies
to all the glib/gobject/gtk conventions, so the tools for wrapping those to
python provided by python-gobject would be useful.

Besides, if you look at http://live.gnome.org/PyGObject, they are adding
gobject-introspection support. Not everything might work, but many things
probably will and you don't have to write a single dot for it.
