Translating permalink tags

Hi everybody,

I am using WP 2.0 and am looking for a way to replace the English words on my URLs this way:

Instead of http://www.myblog.com/category/DVD

to have http://www.myblog.com/categoria/DVD

or instad of http://www.myblog.com/author/jim

to have http://www.myblog.com/autor/jim

and instead of http://www.myblog.com/date/2006

to have http://www.myblog.com/fecha/2006

Is there a way to get this?

Thanks!
