Selection, picking with PyOpenGL?

I was interesting in adding selection and hit testing to ZOE, and was 
looking at the PyOpenGL wrappers' handling of selection and picking.  I 
see glSelectBuffer to specify the size of the buffer, and glRenderMode 
properly returns the number of hits when put back into GL_RENDER mode, 
but I don't see any way within PyOpenGL itself to access the select 
buffer to actually process the hits.  Is there any way to do this 
without using OpenGLContext?  (If not, does this make sense, given that 
OpenGLContext is supposed to be an additional helper library for a 
gentle introduction to OpenGL?)
