Yes it would be. I've been having a bash at this and there are a 
number of things that need doing. (And it will take a while...)

1) Integrate some form of libdsmcc into the backend.
   - This allows the backend to download all of the objects from the
     object carousel.
2) Integrate an MHEG interpreter into the frontend.
   - This uses and interprets data from the object carousel.
3) Write a rendering engine for the MHEG.

Number 3 really should be done in conjunction with the new UI that is
being worked on. I shouldn't be too hard to have this engine being used
for Interactive TV, Teletext & OSD, as the majority (99%) of the display 
stuff would be common.
