Thanks Tomeu. OK. almost there with the json change (just need to test  
the changes properly). I must admit to just trusting your wise and  
noble intentions on this one ;-) json seems kind'a darkmatter from  
where I'm sitting, not standard in the official Python distributions  
(though it has been included in the default sugar python modules),  
close to zero useful documentation out there (other than a few pretty  
pictures) and few actual python examples (thank goodness for the  
ability to reverse engineer web activity and some rather obscure class  
docs in pydoc). I guess because it's so trivial to those who already  
use it, no one's written much about it (I think some wiki time is  
approaching). Probably an irrelevant change for my current usage, but  
may make sense if someone with larger, potentially valuable, data  
storage copies from my source. ~1hr less beer time tonight, I'm sure  
my liver will thank you later :-)
