Howdy Lucas,
That is a great idea. We are currently working on building shortcodes for our core The Events Calendar plugin, allowing you to embed its view into other pages. Once we are done there we definitely would consider doing Event Tickets Plus as well. But right now we have no concrete plans for those.
What would you use shortcodes for? You mention embedding the ticket form into a given page. How would you picture doing that? Embedding tickets for a single event into that page and specifying which event in the shortcode?
Until though you can always do this pretty easily with PHP, assuming PHP is your forte. We have an extensive API for such things.
Does that all make sense? Will that work for you? Please let me know.
Cheers!
