I tried to provide history as best as I recollect, mostly to be helpful. As I've mentioned elsewhere in this thread, Facebook servers use a Host-owned RTC. Unless someone can speak to non-Power servers that have a BMC-owned RTC, this might only affect IBM(*). You'll need to decide what impact removing this feature may have to you and your customers. If you'd like to put together a proposal and seek feedback on what the potential side effects for specific customer classes might be, I can certainly do that, but right now I don't really have enough information on what the "new" design would be just from those two bullets.
