@phillip, The ravens have answered your prayers:
https://github.com/RavenProject/Ravencoin/blob/master/roadmap/README.mdTheir plan is to swap algos which is just as good as anything

However sooner or later we will be seeing FPGAs or even ASICs where they can remotely update the firmware with new algos, remove algos, etc... So the cat and mouse game is on. I am happy with where this is heading!
