Thanks for the update - it is good to see that there's now a viable
open source project for improving VNC server support on UNIX.

Do you have any plans to implement the VeNCrypt extension in the 
server side ? This is the TLS/SSL + x509 certificate extension we
have standardized on for QEMU, Xen, KVM and GTK-VNC (used by 
virt-viewer, virt-manager and vinagre clients). I would also like
to add it to the GNOME VINO, since VINO's own TLS extension is flawed
by not using x509 credentials. That leaves TigerVNC without a good
interoperable TLS extension, so it'd be desriable to implement VeNCrypt
there so we have a consistent TLS extension that's interoperable
across all the VNC clients & servers in Fedora.

Following on from that I also recently defined & implemented another
VNC auth extension based on SASL. This provides for a good extendable
authentication capability, most importantly including GSSAPI Kerberos
for single sign on. I've got it implemented for QEMU, KVM, GTK-VNC and
VINO already, so again it'd be good to plan for adding it to TigerVNC
too so we have a widely interoperable strong authentication system.

Daniel
