But does it really help if you don't have the generator?

I don't use UUIDs much myself, but I think in all cases I've seen that
use the uuid type in SQL Server they're also using the generator function.
Those that just store UUIDs in the database often just uses varchar - in
order to be more portable, I guess.

Not saying it wouldn't be good to have uuid for portability, I'm just a
bit unsure of how much use it is without a generator function...
