1. People that do not have control over the reverse lookup seldom have
control over multiple servers and seldom require to distribute load
2. The script should be allowed to connect to its origin server (as
unsigned Java applets are allowed to, today).
3. Hosting providers will add tools allowing their customers to
configure this security framework, if it is required - but again; if
you are on a shared server you most likely will not need to connect to
multiple servers. It will also usually suffice to have a proxy on the
server (like many people do for XMLHttpRequests now).
