There is an open-source VNC client implementation in Flash, namely [login to view URL] Initialy it consisted of a VNC viewer version and a player version (for playing back pre-recorded VNC sessions). Unfortunately, the player version is not maintained anymore.
I would like you to port the player to the latest flashlight-vnc codebase. The old player source code can be downloaded from [login to view URL] (see version 1.2).
