Get yourself a copy of TinyD, a duplicatable content module. All they do is basically allow you to create custom html (static) pages for your site.
In TinyD (and some of the others) you have the option of 1. creating html pages directly in the module (ie. typing your text into a submission form), or 2. preparing a html page seperately (maybe in an editing program like Dreamweaver) and then uploading it into the module ('wrapping').
Generally they are for use with static content only. Some of the links modules have the option of showing the linked site in a frame, so you might be able to kludge dynamic wrapping that way (or someone else might have a better idea).
