This is a dangerous suggestion, but you may want to look at the source code for
my Acoustic Measure activity:
http://dev.laptop.org/git?p=projects/acoustic-measure-activity;a=summary

My code is directly based on HelloMesh, but I needed to send binary data over
the Tube.  The answer to your question specifically is basically one word:
base64.  Python has a base64 module providing b64encode and b64decode functions.
 I used these to send arbitrary bytes over the Tube, which only supports utf8.
