I think you're probably right, though I can't be sure until I see an
actual implementation.

How about writing a fragment shader? I don't know whether this would
work or what performance would be like, since I don't have a lot of
experience writing shaders. In any case an FBO is probably fast enough
for whatever amount of particles you want to throw at it.
