Actually, one of the original motivations for this idea was Wolfram Alpha's "show steps" feature for integrals. I agree that this isn't useful for the heavy algorithms, but if we had heuristics to solve integrals "by hand", we could use this to show the user how it is done, either through some low tech printing to the screen or some more high tech interface (like something in SymPy gamma). Of course, just as with wolfram, if the by hand algorithm can't do it but risch or meijerg can, we would then just show the result without any options to see how it is done step by step. To clarify what I said earlier, this is a useful idea if you do the right thing, but as it's currently written on the wiki, I don't foresee any high quality proposals for it. It's too open ended, and sounds much easier than it really is.
