Thanks for the information, Fredrik.

No problem. I'll try to provide a minimally-invasive patch to address  
this issue (it's really simple to do -- the code just needs to pass  
the correct byte order to Unpack.c, so hopefully this will count as  
'low-hanging fruit').

Thanks for the info. I'm glad to hear about the upcoming changes for  
1.2, and would be happy to help with some of that if I can...

I'll also try to provide a minimally-invasive patch here too.

Does this count as low-hanging? I'd be happy to send a patch if it  
would be useful; otherwise I'll just put it into my code where it  
interfaces with PIL.

Great -- I'm looking forward to 1.2!

Thanks again,
