I read somewhere that the copper based anti seize is the right stuff for titanium.
I read somewhere else that the copper based should not be used on aluminum.
Is all that correct?
IF all this is correct, then Al mated to Ti should get . . . what?
Any advice appreciated.

I use a nickel based anti-seize based on years of working on marine engines that marinated in salt water. We were taught not to use copper on marine stuff due to potential electrolysis. Not sure if that would cause any issues with Ti since it's an inert metal but the alloys used in Ti might.

I think the issue with Ti alloys used in bicycles is the Vanadium.
Most stuff I read says DO use copper based (like finish line's product) with Ti.

Have only ever used the Cu based stuff on Ti/Al interfaces. Never had any problems in 10+ years.

You need to consider the redox potentials. http://en.wikipedia.org/wiki/Standard_electrode_potential_(data_page)
It's like plumbing. Sometimes you need a sacrificial metal added to the system to corrode instead of the critical components.
Aluminum does not rust. It forms a stable oxide. But look at the bottom of aluminum frames in salted areas. They corrode like crazy.
