I am wondering if you can create a webinar plugin

Please look into developing a webinar plugin, that can handle live and evergreen webinars (through google hangouts if you please), with a live chat function in the live interface, an integration with e-newsletters and external folks like MailChimp / Aweber, and something that can take payments for paid webinars via MarketPress?
Could it also integrate to the new free automation from MailChimp! So the webinar can be seen as an "event" to manage the firing of the automated emails.
