Gsoc - Slicing Tool

Hey there!
Iam interested in this year gsoc. I would like to take slicing tool idea which I heard that its one of most requested features. I get the main conept of this tool. Ive tested guillotine action and slice filter on compiled trunk version. I found that slice filter still have some issues. On irc I was told to talk to ,,guiguru" which is mitch? about gui for this tool. Do you have any comments about slice tool ? I would love to hear some feedback.
