I must agree with Whize that the Tower of Ghenjei is the most over looked feature in the book(s). On the foxey side you make deals, and as Mat said "they cheat." I also noticed that Robert Jordan likes to put limitations on things and when he does he says so, he did not say what the limits where in Finnland. So working off this theory and the fact that the snakey side can answer any question (some might cost you your life), we can assume that the foxes can make any deal. So if you go in there and ask for them to cleanse saidin, what will be there price?
wotmania says: True, Jordan has not done much with the Tower of Ghenjei to this point. The foxes curing saidin is possible, but I lean towards the taint being removed when someone takes a hammer to the seals. Interesting idea, though, that had never really occurred to me.
