See the Help activity in 8.2.0, it instantiates the WebView from hulahop
that underlies Browse and points it at help/XO_Introduction.html.
But is it so bad to make your "HTML-based application" an installable
collection that shows up in the "OLPC Library" navigation on the Browse
home page? See <http://wiki.laptop.org/go/Creating_a_collection>. Just
because most library content is static non-interactive ebook material is
no reason really cool browser apps shouldn't go in the OLPC Library.
One thing that might make collections more appealing and feel like
applications is if the collection's library.info icon (which seems
otherwise unused?!) or the web site's favicon would appear in the
Journal instead or as well as the generic globe icon of Browse. I filed
a confused ticket #9188 for this enhancement.

The WikiBrowse activity (WikipediaEN.activity on G1G1 8.2 laptops)
starts a local python Web server and fires up a WebActivity (Browse)
instance pointing at it.
Better, Browse's engine is XULRunner 1.9 and it has support for most of
the HTML 5 offline application spec
E.g. http://starkravingfinkle.org/projects/offline/todo.html is an
expanding form you can fill out while offline that will update the web
server when next online. It should work on an XO (I can't try it, my
wireless router is bust! :-( ).
I concur with where you're going. *Never* ever bet against the browser.
Browse or a custom WebView activity can do everything that Firefox 3
can do, without worrying about compatibility with abysmal MS Internet
Explorer that's keeping the web stuck in 2004.
E.g. http://wiki.laptop.org/go/FindTheCountry -- why bother with crappy
static PDF atlases when interactive technology like that is available?
And you can View > Source it!
