Mark,
Complete stranger $0.02, I like number 3 the best. Using number 3, I would not take out the "by" it flows with the rest of the logo well, using one of the other ones, I probably would take it out. I really like the line in 3, it helps balance the overall look and helps draws your eye to the center of the logo, otherwise as Count said the W would. You may want to bold the line just a touch if the W is pulling more attention though.
Also, I really like the ghosting of your mark from number 4, but as another idea, you could always put that as a ghosted background on your entire site page, much larger obviously. And if you made the background not scroll so that you are using only one frame, the text would scroll in front of it, your ghosted mark would always show through on the screen.
Obviously my own opinions.
