Exactly that, I am raising issues. I don't have a clear enough 
picture of what RunRev envisions for the player in their product 
strategy; it will surely be the runtime environment for stacks 
produced in DreamCard, but I suspect that a number of people using 
Rev will also opt to distribute their products as stacks, like it 
used to be with HyperCard player. As we know from past, players are 
funky beasts, solving many problems but creating a number of new ones.

In terms of saving, the issue is whether implementing it can be 
really postponed. In terms of externals, RR must decide between full 
security and functionality. I'd like just to know what the sandbox 
is. I gather we will be able to distinguish at runtime whether we are 
in the player or in a standalone, and in the former case, whether 
secureMode is on.
