    the pro's of vmware is that you ship the entire instance to DR and just mount it on your DR vmware host and change the IP. no need to mess with logins or anything else. assuming you have dynamic DNS everything should work in 15-30 minutes since the instance is just a bunch of bits on your network that can be moved between any vmware server

    You're assuming you have (a) the bandwidth to ship it, (b) the server(s) it's hosted on are still up and available to ship from, (c) you have the time to ship it.

    None of those will be applicable if you are dealing with, for example, a fire in the server room, or a power outage you weren't actually prepared for, or your SAN dies because of a 2-disk failure in a RAID 5 array.

    VMotion and other virtual machine movement solutions are really most applicable for moving virtual machines around in the same data center if one of a set of blade servers (or something similar) fails. That helps with a very specific type of DR, but it's pretty much useless in other types.
