Looks like there are two links to the binary patch on the page.  One was 
fixed, but the other (under 'Patching the binary files') is still broken.

This looks good.  Has there been any thought to doing this with more 
than just numbers?

I'm really glad to see the web-based fallback.  I was worried only users 
with new enough clients would be able to access the MUCs.

I noticed in your TKabber example that the user sees the OCR popup as 
well as the link to the web fallback.   Is there a way to make sure the 
user only sees one?  Or is this something that needs to be cleaned up in 
the xep and/or client?   What happens if the user correctly does the OCR 
popup in TKabber, then goes to the link and does it again?


Thanks,


Sean
