My instinct is that this is not possible, but people on here are brilliant. So, I'm going to pose the question anyway.

I have a business account type and a standard user account type. In short what I would like is for the path for business to show their business name (www.mysite.com/?q=users/business-name). For the standard users I don't want an alias. I want it to look like this (www.mysite.com/?q=user/342). Is this possible?

I'm using project/realname for both account types right now. I do want my standard account users to be able to create a username they like. I just don't want it available in the URL for the public to see.
