Enabling "net usershare" in samba

[Sébastien Estienne]

Hello

I'm the author of nautilus-share, it is a nautilus extension that allow 
user to share any folder using samba from the contextual menu.

This extensions rely on a new samba feature (>= 3.0.23) called net 
usershare.

It allows common user to share the folders they owned.

To be allowed to share a folder a user must belongs to a specific group.

I'd like to know if this functionnality could be enable by default in 
samba package.

regards,
