That's my hope. I have one or two ideas that I haven't seen elsewhere and various other ideas that I hadn't seen elsewhere until I looked at certain esoteric frameworks like Yesod (plus a couple of other Haskell ones and Ur/Web), as well as all the normal ideas. Three of my key goals are speed, safety and correctness, all things that are simply lacking (and often drive people away from them in the end) in frameworks like Ruby on Rails and Django (which, incidentally, has been my preferred framework with Python as my preferred language).
However, before I can build the web framework I want in Rust, I'm having to write the HTTP library I want in Rust (with similar goals), and that's the stage I'm currently at: http://github.com/chris-morgan/rust-http.
