Thanks for the comments, I was looking at the glass taxi but was concerned if the 500/4 with a RRS replacement foot would fit. The only other, lens only, solution I have found is Nikon's lens bag. But the Nikon bag does not appear to have much, if any padding.
If you want a padded carrier, I loved my Kinesis. I also had a Domke Long Lens Bag that I used for many years prior to the Kinesis. The Domke is not padded, though. When I get another long lens, I'll get another Kinesis.
I use the streetwalker harddrive, takes the 500 with d3s body on it (hood reversed) as well as a second d3s body, 70-200 2.8 and a few converters and other bits. Yet still looks like a pretty small bag
