are you sure?  does it implement the bf_getreadbuffer slot?  afaik, 
afaicr, and from what I can tell by looking briefly at the sources, the 
binascii.b2a_base64 function uses the the s# marker, and that argument 
type accepts strings *and* read only buffers, right away.  no extra crud 
should be necessary.
