I just noticed a posting on Nabble that I didn't ever see on our mailing list. Here is an answer.

Is it possible to run Mahout on Google App Engine and take advantage of the distributed environment? Thanks in advance, Damiano Spina. I don't think that this will work very well at all for much of Mahout. You can probably embed small classifier models in an AppEngine program, but the AppEngine restricts file storage very severely so it is very unlikely that you could run any training algorithms or recommendation engines. For sure, the experience would not be one suitable for a beginner. What I would recommend is that you put down a dollar or two and buy some time from Amazon on EC2. You can do some very large problems that way for a cost that is remarkably close to zero.
