This will create some new challenges, since we have never had a plugin that
included non-Midas content before within Midas (at least that I am aware
of).  We will enjoy working through the options with you.

My opinion is that you are best off launching your application in a
separate tab/window, especially given that you have a 3 week deadline, as
this is the easiest.  Then after that is working, you could look to
integrate it in with the Midas display, which would give your users a more
coherent experience.

Just from a UI perspective, I'd suggest doing it in an overlay page
launched from Midas, since Midas has a lot going on with the UI as does
your application, so it might be confusing to present them both, one inside
the other.  You'll need to think through how to start Annio, pass control
to it, exit (or at least stop displaying Annio), send messages back to
Midas, and pass control back to Midas.

Good Luck,
Mike
