Base85 encoding (see e.g. http://en.wikipedia.org/wiki/Ascii85 ) allows a tighter encoding than Base64: it has a 5/4 expansion ratio, rather than 4/3.
It is used in Mercurial, git, and there's another variant that's used by Adobe in the PDF format.

It would be nice to have a Base85 implementation in either the binascii or base64 modules.

(unfortunately the Mercurial implementation is GPL'ed, although if we want to copy it we might simply ask them for a relicensing)
