Well if it's 30 seconds, I think a 30 seconds 'synchronising state  
with MP server' would be fine for most people - especially if it  
happens in parallel with scenery loading.  If it's more like two  
minutes, then it certainly needs some thought, but I'd rather have a  
slightly sub-optimal UX for this case, but support event-drive props.  
(Especially if I want to centralise ATIS / active runways / navaid  
idents in the future, as John Denker has suggested before)

Another option is for the MP server to cache all the props from each  
client, and allow clients to request a 'burst' of the cached state  
right after they connect, but before the normal updates start. I don't  
know how the MP server->server tieing is implemented, but I suspect  
such a cache would also be valuable in proxying event-driven props  
between servers.
