It'd be nice, but I wouldn't count on it happening too soon: the necessary APIs don't seem to exist.

It's based on the gdata-python-client library (http://code.google.com/p/gdata-python-client/) for accessing Google Data APIs, and the complete list of them (http://code.google.com/apis/gdata/docs/directory.html) doesn't include Gmail/reader. It does include a bunch of things that this doesn't support yet though.
