BuddyPress.org

Hi guys, I start learning buddyPress its awesome and seems it will give big support to my dream site which will launch soon 🙂 well guys can you guide me how to change dynamically member profile url to subdomain like url. example

Original profile url:
http://buddypress.com/members/demouser/

need to achieve this:
http://demouser.buddypress.com/

and for all members:
http://buddypress.com/members/ which is already happening its fine.

So i want do subdomain like user profile url but can’t figure out to do this.

Community i need support from you for this 😀
