VMware, have your ears on? Customer feedback... Going to VC for EVERYTHING is bad karama. Please design VI ToolKit to support direct ESX query and interaction as well. Use the above thread as reference. For us, my organization, we ALWAYS prefer to talk to the ESX host before going to VC. VC does not scale well, and does not always respond as expected, these are known issues, so we have to go to the ESX host consistently. Not to rehash VC issues, which are well known, but to point out that even with ESXi, we expect to always have the option to go the the ESX host, and not be locked into using VC. This includes a better way to cache credentials when talking to ESX hosts via VI ToolKit.
