> While I applaud competition among browsers, I think that the renderer/webengine is such a big external component nowadays (especially if you lump in the JavaScript engine) that it might be more accurate to say that you're providing a skin, rather than a new browser.
Makes me think of NeoPlanet. That was an online trend that ripped through my university[0]. NeoPlanet was billed as the "world's first skinnable browser", and Wikipedia attributes the coining of the term "skin" (in the UI sense) to NeoPlanet's developers[1]. But NeoPlanet itself was pretty much a skin over Internet Explorer's browser engine, embedding a COM component of the browser into itself. So to me at the time, it didn't count as a separate browser, just a UI for internet explorer.

[1] I think Winamp's use of "skin" preceded NeoPlanet's, by analogy with Quake "skins", textures that could be applied to your player character in the QuakeWorld online multiplayer service, which could be used to indicate clan affiliation, etc.
