I've recently stumbled upon a project called noVNC that promises to implement a VNC client using HTML5 (WebSockets, Canvas) with encryption (wss://) support.

As it's an open source project, I think it would be a worthwile addition to the PVE web interface, which is not usable on mobile devices currently due to the Java-based VNC client.
