That's true, at some size you'll see artefacts, but it's a lot less than with a bitmap and so long as the spline rendering has a high degree of accuracy it should look pretty smooth.
You really would need a system that loads the scalable font and converts it to splines so that you then render the splines in realtime, rather than a pre-polygonized polygon model.
