Now, this is news to me.
Tavia seems to be another KDE web browser.
I say nice.
Semi-related:
Because of a question on the PyKDE list, asking for a more complete HTML widget using Qt (not kdelibs) I am looking at kdenox, which is supposed to be a Qt-only (QT/E) konqy. Perhaps ripping off the khtml piece of it won't be too hard, and then it can be sip-wrapped.
Probably nothing will happen with it, but I am looking ;-)
