That's true for all the straightforward methods that I know of, too.
Cass Everitt has described an implementation of order-independent
transparency that runs on the past two generations of hardware. You can
find a description here:
http://developer.nvidia.com/object/order_independent_transparency.html
I believe there are more recent improvements, but I can't find a
reference online at the moment.
I don't know if anyone has applied this technique to antialiasing. The
big concern is that since objects have to be drawn multiple times,
immediate-mode apps need to do that explicitly, or you need a
scene-graph type software architecture that does it implicitly.
