Profile Custom Fields and Pathauto

Is there a chance to have URL aliases for custom fields in the Profile Module?

I have defined "Interest" as a custom field. Now I want to change the normal path:

- http://mydomain.com/profile/profile_interest/drupal

into:

- http://mydomain.com/people/interest/drupal

I had a look at the code of pathauto. pathauto_user.inc works for Users. There could be a pathauto_profile.inc for Profiles. But I'm not quite shure how to do it.

There's a discussion in this list below for hook_pathauto. Yet it applies to Drupal 4.7

Anyone an idea?
