[dojo-contributors] Allow multiple dojo versions in a page for 1.1?

[Jared Jurkiewicz]

As long as we have a way to still define globals (yuck), then I think
we're okay.  That was my main concern, the whole 'external services
require a global function name' issue.  Discussing it at the meeting
would be great, to see if anyone else can think of any gotchas to this
before the change is implemented in trunk.

Sincerely,
