Thanks for taking the time to write the guide. I've used Scapy before, although quite some time ago, and still found it useful. I thought I'd take a quick look at your guide, well that quick look ended up being three hours of me messing about with Scapy!
I've added your guide to my bookmarks and hope you get the oppurtunity to update it once you finish the OSCP (Good Luck!).
I already had these links for Scapy under my bookmarks, but your's is a welcome addition:
