Unfortunately, I don't have anything to reward you with if you decide to take on this challenge except my respect and a free license of Klok (of course that is free anyway but still). So here is the challenge.
As you all know, smooth scrolling didn't make it into Flex 3. You can find some info and a head start at Alex's Flex Closet. If you are currently working on implementing this for datagrids (horizontal and vertical scrolling) and lists with variableRowHeight="true" that would be awesome. If you aren't already working on it but like a good challenge, I'm sure the rest of the Flex developers of the world would appreciate it.
If anyone has something more tangible to offer in reward feel free to comment here.
