  You could always code it up and hope it gets adopted.

  But I don't see it being all that viable for userdata.  About the best you
can do is convert userdata into hex, base64 [1] or ascii85 [2] and hope
there aren't any pointers to other data.  Generalized, it's impossible, but
you could get a (somewhat) useful limited implementation.

	I like that there are 13 different "standard" base64 encodings.
