Well, I've been experimenting with this knot:
http://www.fieggen.com/shoelace/secureknot.htm     So far so good. It seems to be securing the paracord much better than the standard shoelace knot. The only problem of course is unlearning centuries of bad shoelace-tying habits. <img src="/images/graemlins/grin.gif" alt="" /> 
Many thanks to Mr. Ian Fieggen!
