"Meta data" for taxonomy terms?

Hi,

Just been thinking about an idea and wanted to know if anyone has any suggestions for how to implement it.

Imagine I have a taxonomy called "celebrities". People can write a blog post and tag it with the name of the celebrity they're writing about, e.g. "jessica alba". When the post is published, you click on the tag to see all other content tagged with "jessica alba". I'd like to be able to have some information in the sidebar about jessica alba; such as her photo, birthday, official website, fan sites etc. Ideally, this info could be edited by members. What this is creating is meta data for the taxonomy term. Currently you can only create a name and description for a taxonomy term.

Now I could create a flexinode (e.g. calling the node type "celebrity") with all these different pieces of info I'd like displayed...however...this could be a lot of work for me - because each time someone tags a post with a new celebrity name, I'd have to manually go in and create a new "celebrity" node.

Is it possible to add meta-data to a taxonomy term - i.e. extend the name and description to other fields as well? OR is it possible to auto-create one of these "celebrity" nodes (blank, of course)?

Or, is there another way of doing this?

Many thanks!
