Dynamic Font Scaling CSS

I love using the MS fonts for Vista, they're great. However they're several points smaller than the common failsafe fonts, meaning a website optimized for the Vista fonts won't look nice for people with older fonts.

The problem is described in this old article:

It's been 3 years since. Has any solution been found? Thanks.
