I can't ascertain if this matches any of your above descriptions
(although possibly the one quoted is similar), but how about
URL-relative externals? Let the syntax be (regexy):

    Absolute URL [act like svn 1.1]: ^[a-z0-9]+ [...]
    Relative URL: ^[./] .+ [...]

On absolute URL, libsvn_wc works as it presently does. On relative URL,
make a duplicate copy of the URL for the current directory. For each
"../" encountered, remove one URL part from the end of the duplicate
URL. For each non-"../" encountered, append it.

I think this is more or less the same way as relative URLs work on the
web (although I haven't read up on it).

I'm sure this has been discussed already, I'll reiterate just in case:
this would allow for example, a whole svn server to change protocol
without having to rewrite externals, or a dual-protocol SVN server to
have protocol-agnostic svn:externals definitions.

The scheme above would also be unsurprising, for example, for a web
developer who is just starting out using Subversion.
