Yes. I was actually thinking of tunneling the curses data but another option would be a more proper character-based encoding. The advantage of that is that you could also send over fonts.

curses is very un-vnc-like, it's a single stream an you need all of it to get something meaningful. Much more in the spirit of vnc is to encode 'character tiles', and to allow coalesced updates like the regular vnc protocol.

Yes, my main interest in curses was to avoid having to deal with character mapping. I was planning on just using vte terminal to render the data. Maybe doing a proper encoding is the right thing to do though.

Ah, CGA as in color graphics adapter. Why not add the encoding to vnc and use the regular -vnc option? if both viewer and server support the feature, and if the display is in text mode, it would be used automatically.

Yes, this is what I want. I still want to be able to connect to it via telnet though independent of VNC.
