I don't really know all those KHTML internals, so I'm CC-ing the KFM 
development list, but it sounds like the way to go to me. When I added the 
media support to KHTML I tried to make it as generic as possible and not 
specifically tied to print and screen, so I hope it is possible to implement 
this dia show mode in KHTML as well :-)

If some of the KHTML gurus could comment on this...
