Hi John,

This is a great idea. As someone who works a lot with the open data
community in Montreal, I have been struggling to offer solutions for
this type of issue. This just might be the type of proposal that could
help them get how accessibility for the blind can be part of their
projects. Plus it has the added bonus of being cool. I hope you keep
this discussion on list or at least somewhere public so we can all
benefit from this discussion.

Best regards,


Catherine
