Leopard syncing

Hi,

It seemed during the "Tiger era" that we were encouraged to use the truth database to keep common data types synced ( address book, calendar, bookmarks, etc), but not our own data types. This made sense, as we would be storing all the same data twice - once in each format - not to mention the unknown number of times it would also exist on additional synced computers. With Leopard, it seems that we are now being encouraged to use Core Data and the new very handy sync features to give our apps the ability to use the sync engine and stay synchronized across multiple machines. This sounds both wonderful and wasteful. The main question is this -- am I correct about this interpretation? Are we now encouraged to put copies of our data into the truth database? Is there no concern that it will become HUGE? I don't care, if you feel the truth database is set up to handle it.

Also, if we use the truth database to stay synced, how does that work with 3 computers, say one at home, one at work and a laptop. I'd like to keep them all synced, so how many copies of the data exist? Doesn't each machine have a truth database? Whose rules? There is a mention of designating a "master truth database," but it isn't clear how you might do that, unless it is just a procedural thing the user needs to be aware of.

Thanks,
Denise
