for the most static models i use displaylists, but how can i
speed up dynamic models? is that where VBO's would come in handy?


Yes.

if i would use VBOs instead, i would still have to access the data,
so it won't help having it in the memory of the card, would it?

You have it in main memory and copy it to the VBO.

PS: Never read from a VBO - it's very slow, only
write to them.

In science it often happens that scientists say, 'You know
that's a really good argument; my position is mistaken,'
and then they actually change their minds and you never
hear that old view from them again. They really do it.
It doesn't happen as often as it should, because scientists
are human and change is sometimes painful. But it happens
every day. I cannot recall the last time something like
that happened in politics or religion.
