something like one of those mail clients that will display HTML content
with images and other media that are included as attachments to an
email. The program on the Moon wouldn't make its own requests for things
like image content, but only display what gets passed up to it from the
Earthside browser.

It doesn't sound you're really describing anything different than Ben Bradley described; you don't need a browser to act as this intermediary. In fact you don't want a browser, because a browser implies something that turns the content into something displayed to the user, which is not something you need or want to do at this stage. (Hence why I presumed you were talking about sending a realtime feed of what the browser rendered.)

Even a caching proxy could easily be extended to have this kind of functionality. As it is, when you a hit a URL that's not in the cache, you are shown a 5xx HTTP error and are told to check back later. The proxy then makes the request for the content of the page. When that request finally comes back, then the proxy processes the content that came back (probably handing it off to another process), which then makes supplementary requests for everything directly referenced in that page, then perhaps supplementary requests for everything directly referenced in _those_ pages, to whatever extent you want.
