> Rainbow tables have been "eclipsed" by the rapid progress of GPU-based parallel brute force attacks

The time-space tradeoff goes both ways. By using GPU instead of CPU for the time-intensive parts, you can increase the storage efficiency of rainbow tables (generate longer hash chains); the speedup would still be the same proportion. However, I don't know whether there are any actual implementations of this.
