[TYPO3] How do handle a URLs like www.mydomain.com/fe_user_name

[Fabian Fisahn]

Hello Group,

I have a site with registered frontend users with own pages. Now  I want
to realize a direct access to their profile pages with a url like
www.mydomain.com/fe_user_name. This should be similar to the Myspace URLs.

Could somebody give a hint, how to do this? Is it possible with a hook
for realurl? What is the best way to implement this?

TYPO3 4.1.3
RealURL 1.1.4

Thanks
Fabian
