I’ve tried many different methods for font replacement on my site. I just can’t help wanting to use a fancy font. I just switched techniques, but here is the complete rundown.
sIFR. A Flash implementation that changes your tags into flash movies. They can be selected/copied, which is good. WordPress plugin here. Feed your TTF to this tool and get the SWF. I had issues in font-size. Also, it seemed just as slow as Cufon, if not slower.
I also added in my own drop down box at the top right of the blog. It uses jQuery and the Cookie plugin to let the user select a font. I used PHP to read the cookie and build the CSS for the page on the fly. It seems to be working much faster and the implementation is pretty easy.
I imagine a wordpress plugin could be made to automate this. You upload a TTF and it generates the EOT, saves it to the directory and makes the CSS on the fly. Hmm, maybe someone will make it.
