Hi,

Well, the DOM doesn't capture all the relevant information. I'd like
to be able to roll back JSObjects as well:

obj.foo = "bar";
<store rollback point>
obj.foo = MD5(obj.foo);
<rollback>
obj.foo == "bar";

It would also be very nice to be able to save state to disk for
restoration in a later process.

Thanks for your quick responses, Brendan. As always, your help is very
much appreciated!

Cheers,

Eric
