I just bought a super duke and sold a zx-14, both remotely, and entirely over the phone or forums.
Both me and my buyer used
for shipping. They WILL DO escrow too, for a fee of course.
In both cases we were comfortable enough after a lot of phone conversations to skip the escrow. We did this:
The seller writes a bill of sale, photocopies their driver's license, the title, and faxes or scans and emails them to the buyer.
The buyer overnights the funds.
The seller overnights the title.
Shipping company picks up.
In both cases we spent considerable time on the phone and felt comfortable with the transaction. There was still plenty of risk for the buyer though. Escrow would be the safest route.
I've used uship a couple times, and neither experience was great. One shipper wasted 6 weeks of my time and never picked up. The next had my bike barely strapped onto a hay hauler. It made it but I wasn't impressed.
1AA costs a little more than uship typically, but not much, and they ship a LOT of bikes. Both pick ups and drop offs were timely and both bikes were undamaged.
