Thank you very much. I will certainly give it a try today, it seems to be one of the most popular on this site and I was rather let down I couldn't afford it to begin.
The guide I had followed had you unbind the movement keys in the second client in order to use all movement key strokes to refresh the follow command for that client. While I certainly don't understand all the mechanics difference in how HKN treats movement keys, I can say that the setup was working for me for several hours of game play and even allowed me to have the characters move and jump accurately together. As I stated above I'll be working with ISBoxer's trial today, but if for some reason that doesn't work for me I will certainly check the guides you linked.
Again, to all who have commented and been so helpful, I can't thank you enough.
EDIT: Having now tried ISBoxer I can't say enough how much I enjoy this software. It has made me contemplate continuing to multi-box even after the benefits of my current RAF expire. I had a very bad moment with their IRC support channel during setup which very nearly brought the whole attempt to an end and will be submitting a ticket to the author to change the login to reflect that it wants you "email address" rather than username or to change it to accept username but otherwise it's been a very enjoyable experience. Mirai's tutorial videos can not be over appreciated as they walk you through the entire process of setup. Initial setup is both far more complex but also easier than HKN as the basics can be done via a simple wizard. I'll stop preaching to the choir on this one, but thank you all for helping me get this all set up and working.
