Don't forget hping, it allows you to construct just about any type of packets you'd need.

Also people should probably look through Dan Kaminsky's 2006/2007 Black Ops of TCP/IP talks. Both hit on some technical things you can do to detect unwanted ISP behaviors. The slides are available at 
http://www.doxpara.com/ and a video of the 2k6 presentation is at video.google.com/videoplay?docid=2235822817954898588
