Calendar/events with 3rd party integration (GoTo/citrix)

Is it possible to write plugins for events/calendars in EasySocial? We are using DPCalendar and wrote a GoTo (training/webinar) plugin to populate trainings from an account and it just uses ical syntax to build events dynamically.

Is it possible to write such a plugin for easy social at the application level for individual users, but also maybe in a more public facing way for the site where we would show one account with events for a "site webinars" being hosted?

Or if we do it by user, is there an easy way to publish a single users calendar in a visible area instead? We're trying to re-create similar effect as dpcalendar where we can write a plugin, get third party events, and show one central calendar on the site for GoTo webinars.

Thanks.
