I am not sure I would count John's story as a success, yet. As he says, "We have been in pilot phase for about 6 months now and look to moving our editing to production after the summer." He seems confident, however, so I would count that as a plus for fabrics.
My real concern in seeing the two testimonials here is that both of these localities have teams of parcel editors. Again, we are a small county with approximately 10,000 parcels--an order of magnitude smaller than Denver with 450,000 parcels. We do not have the resources for a 6 month (or longer) trial of the fabrics. Ideally, a solution should just work without a lot of workarounds. In any event, we have entered the 10.1 pre-release program, and will look at fabrics again, time allowing.
