I'm wondering if anyone knows how to connect a bluetooth remote control or headset (such as a Jabra BT3030 which would be perfect as a remote control) with remote controls to control the video playback of the media player?

Use for this would be connecting the N900 via TV out to a TV and watching movies. The normal controls of play/pause/forward/rewind as well as volume controls would be useful. As well as the standard feature of answering phone calls by the microphone (which probably already works). Playlists for videos (eg. music videos) may be needed in future to forward from clip to clip rather than forward within the movie file.
