Database design for tagging

I want to implement tagging on all the content on my website in the same way that del.icio.us and Flickr do it.

I was wondering what the best DB design would be to do this? I figure that FULLTEXT indexing might work the best since they'll be common words and the cardinality would be low.

THe other option of course is a many-many lookup table with proxy tables for all content. Does anyone know how del.icio.us does their tagging database design?
