Great article! One thing I've always theorized, but have never been able to test is the potential downside of using client side dewarped fisheye panoramics use of additional client PC resources when dewarped. I'm sure this is negligible if dewarping one or two, but if you have a large amount of this style camera being dewarped it could be an issue.
The idea is you get more coverage with a single fisheye camera versus multiple fixed cameras which is how you save money with fisheye cameras.

Fisheye camera seems interesting but cost more...
