Any application can work well on RANGI hosts without any change.

For RANGI transition mechanisms, RANGI hosts will initiate communications
with non-RANGI hosts in normal IPv6 fashion (e.g., use one of its locators
for establishing communications), just as dual-stack hosts use IPv4 to
initiate communications with IPv4 hosts, while non-RANGI hosts will initiate
communications with RANGI hosts via RANGI transit proxy, since non-RANGI
hosts take the host identifiers of RANGI hosts as normal IPv6 addresses. For
more details, please read
http://tools.ietf.org/html/draft-xu-rangi-proxy-01.

Yes. Different applications could communicate with different destination
hosts.

No new docs at present.
