Excellent. My favorite implementation of Pong is PLBM Pong from the DOS days: you can make the ball crawl at first and speed up gradually until it's all frantic jiggling of the paddles. Much fun've been had in the two-player mode.

You could in fact do likewise: let the player choose the initial parameters and the speed of change. Maybe with preset difficulty tiers if high scores are kept.
