I am experimenting a feature to implement VNC protocol server based on

Due to lack of document, i am not sure if my understanding to the
interface is correct. Especially, i am not sure the state transition is
understood correctly. If someone in this list can give me a review, it
will help me moving forward.
Current, the patch can work with OSE version as a "Built-in-VBoxVRDP". I
can successfully connect to VRDP with mouse support.

Hi Howard !

There was VNC support for VBox 3.2.x (OSE edition), but was dropped from
v4.x.

I would welcome VNC server back. Is this better to have as pat of the
'core' product or as an extension ?

Nothing was dropped. The source code still contains the VNC code as before.
Users have just to enable it (VBOX_WITH_VNC=1 in LocalConfig.kmk).

That said - the proper way to handle any kind of remote desktop access protocol since VirtualBox 4.0 is via the generic VRDE interface, which has been introduced exactly for this purpose.

The existing VNC code was just left in because we didn't want to lose the code before having the VRDE module supporting VNC.

Doing VNC support as part of a VRDE module packaged as an extension pack is the best solution in the long term, as the relevant interfaces are intended to be long-lived (bear with us if initially we can't quite keep this promise), and that means the extension pack can be truly developed separately, with its own release cycle etc.

We have plans for allowing platform independent executables, eliminating the need for a staged build to get the extpack contents for the supported platforms, but this isn't something which will happen tomorrow. As usual - contributions are welcome. The picture around extpacks will hopefully become clearer once we have a sample in the tree which people can use as a starting point.

Kind regards,

Frank
