Portions of the 'live-wire' feature would be expensive, namely the freezing, edge learning, and automatic node generation. I submitted a patch not to long ago that implemented the most visible part of the live wire feature--the interactive edge--and I was told that it was accepted into the developers version. I have not checked to see if it really is there, but I could send the file again if I can find it. As far as I can tell, the node generation is not that substantial--it is easily done by hand. The learning portion would be tough, and with the current interactive algorithm the freezing would also be difficult.

I think I was the last person to substantially modify the iscissors code. I read the paper you reference above, and indeed it was quite helpful. However, note that their algorithm is substantially more computationally expensive than what iscissors.c currently does. This is deliberate. Also, the "live wire" feature mentionned in the paper would be fairly tough to do in gimp (from a UI point of view). Can you be more specific about what features described in the paper you wanted to add to iscissors?
