Saw this on Lifehacker this morning:
QTWeb, a WebKit-based browser, is seriously speedy, doesn't let its interface get in your way, and can blend into any Windows theme. More than that, though, it has a quick-fire privacy mode.
The browser does most of the stuff you'd want from its portable, no-install-needed executable, including password-saving, tabbed navigation, and plug-in compatibility. The real reason you might use QTWeb over, say, a portable version of Firefox 3.1, is its built-in, quick-access privacy mode, if you want to browse on someone else's system (or your own) and not leave a trace. Firefox 3.1 may have a built-in privacy mode, but if you're looking for a slimmed-down, no-add-ons-please browser for on-the-go browsing, QTWeb's a great choice.
QTWeb is a free download for Windows systems only; make sure to grab the "stand-alone executable" if you're going the USB route.
you can actually try this out it's uses qt like qtweb and it also uses webkit and does tabbed browsing https://portableapps.com/node/17334

I know, unfortunately Arora won't have plugin support (ie. no Adobe Flash) until it's built with Qt 4.5. QTWeb is built with a dev build of Qt 4.5 so it has plugin support.
well then I'll work on a test release then as I did see that it is under an OSI approved license

I was playing with it earlier, too. Seems like a pretty easy one. Just move the settings back and forth. Set the download to ask where to put it. You can do a replace of drive letter on the settings file which will portablize a setting for downloads (if the user sets one) as well as a local homepage. All the code is available in existing apps
Only thing I couldn't find was if you can get plugins to be portable.
Sometimes, the impossible can become possible, if you're awesome!
