NOCACHE forms

I’m working on an add-on that has a function that outputs an html form. The form should not be cached by EE, much like exp:comment:form. In the case of exp:comment:form, it first wraps the tagdata in {NOCACHE_COMMENT_FORM}…{/NOCACHE_FORM}, and then finishes parsing later via EE_Template::parse_nocache(). I would like to do something similar, but it seems parse_nocache() only works with the Comment and Channel classes by design.

What’s the cleanest way to get what I’m after?
