Not sure if this is a pipe-dream, but I am interested in the URL rewriting capabilities (and DNS mapping) of a single-site WordPress install.
Typically in a WordPress MU setup, we'd use WordPress Mu Domain Mapping to map new sites/installs to a domain/CNAME.
What I'd be after is if it's possible to map a single-entity, like a user to a CNAME on the registrar.
For example, let's say we have a bunch of users in a single-site install. Ideally, these users would be accessed via
get_user_by() which is an additional question).
Then, on the registrar level, you setup a CNAME that has a value of
us.OURDOMAIN.COM and point it to the IP address of the site. From there, WordPress is able to determine that
us.OURDOMAIN.COM should load
Any initial thoughts on this would be greatly appreciated. Thanks as always!
