André and myself ( Gregg ) have been looking at various aspects of his Time of Day system that could be used for my Zulu combat simulation library. One such feature is multiplayer support. In order for sun, moon, clouds to look right - the timing has to be synchronized across machines so that players see the same thing at same time. ToD will support such network synchronization. We've talked about a number of other cool ideas as well. Great to work with him, a fellow fan of hyper-reality.
