Out of curiousity, why does this draft refer to the SQL API but not the storage interface?  Is storage not also a solution to local data storage?

Since there was some interest in this draft I got ACTION-58 to address the
feedback given in this e-mail.

I added the two relevant pointers to the introduction section:

This seems to be feedback on HTML 5 rather the note so I'm unable to
address this.

I think "server.cgi" more accurately indicates it takes a URI than if we
just used the "events" so I left at is. (If the technology changes a
permanent redirect can be used or you simply change the type using a
ForceType directive or something like that. Should not be much trouble.)

I like writing JavaScript that way, but I got another example that
included them. So this is addressed now.

This no longer appears in the draft. (It was not a typo though, a mebibyte
is the "official" name for 1024^2 bytes.)
