There are many people still using XP and I can't see that as a problem. Three years is not an eternity - what fraction of PCs currently in existence were bought in the last three years? Not so few that we can treat this length of time as effectively infinite. If IE6 works then why are you so insistent on people abandoning it? Is it to make it easier for those creating web pages? If so, just provide a lower level of support for the IE6 user.
