Does the job very well. Initially I thought it didn't work, but it was only because the default settings tend to make the font render outside the box, try setting Yoffset to 20!
I chose this over my own Flash based dynamic solution because flash just doesn't render as nice (weird eh) and I don't really want to use Flash when an image will do the job. Also copy-paste might work better if when using an image if it has an alt tag.
Some of the problems, sometimes Alt tag is empty (usually) but small hack fixes that.
Some modules change the title in a non-standard way, Virtuemart really messes up with this, it will cache the first heading and keep that - being the same cached filename as the homepage this can be bad because you will see the Homepage heading as "some product name" if the visitor came to your site via a product.
Dynamic article title names work fine, so I think this can be fixed.
