XriAsRelativeUri - Question of Bindings

In section 6 - "Proposed HTTP and HTTPS Bindings"

http://wiki.oasis-open.org/xri/XriAsRelativeUri#head-66cc964a3fdc2ada8ed087e2bd95bca22944b7c9

What exactly does *.xri.net do?

If the "*" means I can put anything there, does that mean all of the  
resolution happens on the "*" server?

Also if I designate a server (or group) with sub-domains to do  
resolution work... ie. employees.example.com and parts.example.com ...  
under the "same domain" proposal can I split that work up? And would  
it become something like  http://employees.example.com.xri.net/=nika.jones 
  right?
Wow.
