port selfupdate, rsync, and tight firewalls

With all the changes going on with the migration from DarwinPorts to
MacPorts, is the rsync URL going to change when doing a selfupdate? 
Currently it is pointing to
rsync://rsync.darwinports/org/dpupdate/dports.  I need to know.  The
company I work has a very, very tight firewall that blocks rsync, ftp,
and a bunch of other stuff.    In order to get access to those protocols
I have to request each port to be opened.  On top of that, I also have
to let the security folks know which server(s) or domain name(s) they
can talk to so that access can also be restricted.  Hence, why I need to
know if the URL may change, especially the domain name.

Argh....  Yes this bites, but it's better than finding each dependency
for a piece of software and building by hand.

** Note to port software makers: Don't always list your ftp sites
first, second and so on.  Try to putting an http site as the second
location for the code source archive.  **

Thanks,
