It is! If I didn't remove the bag so often... that's how I'd have mine mounted permenantly.
It doesn't look too bad to slip the side straps under the seat when the bag isn't on the bike. The left side strap is more difficult to push between the subframe and the battery box when installing, so I'll often just leave the straps on.
probably too late for the page 1 purchase consideration, but for the forum, and fwiw, i have the BMW tail bag and a kriega R35. I usually take one or the other but have been able to ride with both no problem. I use the tail bag preferentially and it works great for daily commute and for one or two "overnights". It holds more than you think if you are clever in how you pack. For anything longer, or if I need to lug more stuff (like gym stuff), then I go for the Kriega (or both). I also have a Timbuk2 messenger bag which I sometimes use for quick trips.
I will probably get one of the Kriega bags also, they look like a very well built backpack. When I do, I want to make sure that it is high enough on my back so it won't hit the tailbag if I'm using them both. The tailbag hasn't left any marks on the plastic so far, and I have kept the useless passenger seat to better conform to the shape of the tailbag. I think the seat helps keep the tailbag in place and more off the plastic.
I like Woodcraft products and have his rearsets, case covers, and frame sliders. Since the sliders are designed to stay as close to the frame as possible, the right side does need some slight radii cut into one of the slots as you can see in this picture. Pretty easy to do and not all that noticeable.
