I wasn't for sure where to post this, but I came accross http://www.mathjax.org/" [Broken] requires). It's based upon Ajax, which allows web browsers to display HTML while loading things in the background (similar to something like Gmail). This is the best solution I've seen so far, although like they mention on the site, it hasn't been optimized for speed yet. Like most math/physics based sites, PF currently outputs image files, which have the restrictions of being slow to load, subject to weird distortions in the LaTeX output, and the inability to scale as the user zooms in or out like HTML does. I've been looking for a solution like this for a while, because currently, there really isn't a nice one out there.
