My bet is that if we change a tile it will likely have to retransfer the whole thing, especially since we are compressing the files on disk. But to me, the main feature of rsync is that it does everything and I don't have to think about how it works or reimpliment it myself. :-) Regards, Curt. -- Curtis Olson IVLab / HumanFIRST Program FlightGear Project Twin Cities [EMAIL PROTECTED] [EMAIL PROTECTED] Minnesota http://www.menet.umn.edu/~curt http://www.flightgear.org _______________________________________________ Flightgear-devel mailing list [EMAIL PROTECTED] http://mail.flightgear.org/mailman/listinfo/flightgear-devel
