I've been continuing work on the embedding widget. It's starting to come together. The code that actually loads that looks like this:
Minus the usual packing into a container and showing the widget and stuff. You still can't click on links but that's not a problem with my embedding widget.
By the way, you can do <pre> on advogato with this:
<div style="whitespace: pre; font-family: fixed">Foo</div>
Or, if you're really nice you can leave out the font-family: fixed ( like I did above ) since it doesn't fit with the motif here.
