Dynamic QueryConnect based on IP adress (like in RealVNC 3.3.x)?

[Michael Reitz]

I just installed RealVNC 4.0 and while experimenting with the new features
and options I finally discovered that the question mark is no longer
supported in the new Access Control list (Hosts).
In RealVNC 3.3.7 (and older versions) I used something like
AuthHosts="?:+10:+192.168:"
in order to automatically accept connections from private IP addresses, but
ask the user for connections coming from public IP addresses.

Now - in RealVNC 4.0 - there is only the static QueryConnect setting left,
which doesn't allow me to setup the scenario described above.

Could the question mark be reimplemented in the new Access Control list?
