+VNC server does not work with Mac Screen Sharing
+
+When connecting to a QEMU instance from a Mac using any VNC settings on the QEMU CLI and any target arch (ARM, Intel, etc.), the connection is attempted but the negotiation never finishes.
+
+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.
