A better way to insert preformatted snippets into content/wysiwyg? Is there a way to insert pre-formatted objects (like a standardized sign-up form) in line in content via wysiwyg (a'la the fantastic wysiwyg-templates module), but encapsulated and protected...

I actually love that w-t can insert snippets, and will continue to use it, marketing likes to insert the same search form they always use and then change 2 words to test if that drives conversions.  For what it does, w-t is perfect.

HOWEVER...

Having done that, I now want to pop in content in exactly the same method, except LOCKED so it can't be edited, but so I can still SEE it, and potentially move it around the page as though it were an image.

I'm not expecting too much for response, but if I end up really needing it I'd rather hear what other ideas are out there than build something myself that has already been done.

(background to be posted in a comment below for context)
The perfect solution hasn't presented itself, but I settled on using specialized content types inside a parent content type, (via Entity &amp; Entity Reference fields) and then using Better Formats, Wysiwyg with CKE, Fieldgroup, Conditional Fields to make a user interface that presents all the myriad options in a nice clean manner.

I'm kinda proud of the result, I expect I'll eventually reuse the system somewhere more public so I can show it off.
