I've not heard of any problems with Ti-Ti.

It certainly happens with ti bolts in ti threads - the molecular surface of ti is very 'spiky' which is why titanium is dull in its natural state, not shiny like steel or ally. These spikes bind the bolt and thread together, so I'd imagine the same would happen with seatpost in a frame. I'd imagine a healthy dose of copper grease ould sort it out though.
Yup, keep it cleaned and greased regularly if no sleeve, but certain types of grease are made for different types of metals when used together. I do believe I read somewhere that copper is the magic metal for ti. Some types of grease have a whole buffet of metal ingredients...sort of a do it all.
