Very nice tutorial indeed. Nice blog too, I've bookmarked it. ;)

Also, does anyone notice that even when you think you've planned everything out to perfection, that you find some answers at the oddest times? For example, you'll be doing something completely unrelated to programming and suddenly it hits you, a faster and more efficient way of solving a problem you've been dwelling on for the past few days. Happens to me all the time! The odd thing is that the aforementioned scenario happens more often than not while I'm showering. ;)
