If you already have a 400 and an 800 FW cable, all you need to do is cut them in half and use some duct tape. I'd recommend tying the cut ends together before covering with the tape, that will help protect separation should they get pulled at both ends at once.
Remember, you can now get duct tape in many decorator colors! Be sure to get one that your wife will like!
Always good to keep the wife happy.

800 cable. The Sonnet box should solve all the issues, (at least the ones I have identified so far) and the price was only 24 bucks shipped.
Now I just have to adjust to all of the nuances of "snow" and see if I can transfer that bit of knowledge to "Momma".
She will be traveling with the MBP now. (sure is a neat little guy and I love the lighted kbd)
