You could easily make a plugin to add the shortcode when you click a button in tinymce... I made one to add a shortcode to include youtube videos. Ill attach it when i get to a computer where i can access it. If nothing else you can use it for reference.

Here you go... I just whipped up the included instructions (ReadMe.txt) now, so If I made any errors let me know and I'll fix them. There's always room for improvement, but it gets the job done. Hope you like it.
