Of course MT applications need to share data! Sorry, I think you misread
what I wrote. I wrote:

"If you are going to share mutable, sequential value types..."

And then proceeded how to show how you share data in MT applications by
demonstrating mutable, guarded object types, and discussing the implicit
shareability of immutable objects.
