I've taken this back to the users list, because I don't think we're
really at the point of proposing a change to Subversion.

This is most likely done using Kerberos, if I understand correctly. If
I'm right, then your local machine caches a credentials file which is
valid for a limited amount of time, and does not contain your password.

There exists a standard for performing Kerberos authentication over
HTTP, and it's implemented by an Apache httpd module as well as some web
browsers (IE, Mozilla). But neon, our HTTP client library, doesn't
implement it currently. So one option would be to look into
implementing this in neon.

There are also vague plans to add Kerberos authentication support (among
other forms of authentication) to svnserve, using a SASL
implementation. But they've been stalled for a while.
