OK...  I was so naive... I thought GemStone could move the objects over the
wire automatically. Why I thought that? Because if you have a remote node
where you have other gems running and a share page cache etc...you move
things over the wire to the stone node... but ... maybe at this point the
swapping unit is pages, not objects graphs...

If the communication is GemStone-GemStone, cannot I use Passivator (I don't
remember the exact name)?

OK.

Ok...so..just to confirm...GLASS license allows me to take GemStone A and
communicate with GemStone B, but it is my task to know how to pass the
objects over the wire. Right?
