I read Kent Beck's book, "eXtreme Programming explained: Embrace Change" this past week. I just found the Preface on the publisher's web site... it's a great, consise description.

My customer's shop is adopting the XP practices; this is a great opportunity for me to get my feet wet with XP. The only problem is that pair-programming is a core practice in XP, and I work at home, alone, on the other side of the continent as my customer.

I'll be putting on my best Two-Face impression to try to make it work. :)

eGroups has an extremeprogramming mailing list. It's a high traffic list, and the high-priests of XP are frequent participants on the list.
