There is no need to change the protocol version itself to use new encoding, there are provisions for that in the existing one.
IIRC the problem was also that each party was waiting for the other one to send data after the protocol version exchange, but that was 5y ago. Yes it should be possible to work around this, but I don't have a Mac now.

I've verified this when building QEMU from source (1.0 and HEAD) on Ubuntu, Fedora and Debian or when using Ubuntu (Oneiric) and Debian (Lenny) packages. It does not matter whether I specify authentication (or anything else) on QEMU's side, the behavior is always the same - I see the connection being established using netstat and tcpdump, but QEMU does not seem to send back any pixmap data after the connection setup. Best guess as to why this happens is that the VNC negotiation on QEMU does not like the protocol version and VNC encoding sent by the Mac's built-in VNC client, or that its negotiation logic is subtly broken. I appreciate that it's not meant to be a full VNC server, but it prevents me from using it remotely until a stable Mac build is feasible. Background info: Mac OS X includes a VNC client called Screen Sharing that you can invoke in two different ways: * At a terminal, by typing "open vnc://hostname:tcp_port" * From any URI-enabled field (such as the Safari URI field), where you can just type the URI as vnc://hostname:tcp_port Please do not confuse the enhanced VNC protocol Apple Remote Desktop uses with Screen Sharing - they are not mutually exclusive, but they are not incompatible either, since what Apple does is to negotiate extra pixmap encoding and authentication options - I use Screen Sharing to access many VNC servers such as vnc4server, tightvncserver, vino, etc. without any issues whatsoever, so the issue I'm reporting is not an issue with Apple's implementation.
