Thanks!

However, it is currently in "preview release" which basically means "pre-beta", so we don't expect it to be 100% production-ready yet. They are adding and changing features constantly. In fact, many of the problems mentioned in this article are no longer issues. A datastore cursor, for example, fixes the offset limit. A cursored query allows you to skip right to the place where you left off previously, and performs much better than an offset query. The new blobstore api allows entities up to 2 gigs. I'm not sure how this interferes with the 1mb variable limit at runtime, but I'm sure there are some hacks out there to make this work (probably using taskqueue, depending on the job). Although we have encountered various roadblocks, I have maintained my optimism with App Engine for the following reasons: 1. The free quota is enormous and the resources beyond that are cheap. There is simply no comparison to other cloud hosting solutions. 2. Google takes care to prevent you from shooting your foot off. Sometimes they prevent you from doing something because it wont scale. Finding a way around the limitations is the key to making a scalable app. A virtual/dedicated solution assumes that you will have the know-how to scale everything on your own, which may not always be the case. 3. I LOVE Python. My jaw drops when I see someone actually prefer PHP or C# over it. I urge people to take a serious, objective try at Python. You'll never need curly brackets again :) This article is a great outline of the problems that many of us have faced while working with Google App Engine.

I am also curious how google is going to add support for the batch processing. I think it will be some Map/Reduce flavor. It will ve also interesting to estimate - why do they built such strict limitations on thier platform. All points are very valid.
