@Martin: It takes a lot of CPU to do some MapReduce-style batch update
to entities (like "UPDATE kind SET propery_x = value" in sql type of
stuff or delete all entities of a given kind)
So I just wanted to say that some apps are quite expensive on app
engine, no matter how many users you have.
I solve this by deploying the app to each company using it, so they
have full control over the quota and do the billing ;-)
Stability: I had a lot of problems recently like frequent datastore
timeouts, failed put operations because of maintenance periods etc.
but I'm confident that Google will solve this soon and everything gets
back to normal one day.
In general it is quite challenging to develop apps for app engine, but
it is also interesting to learn a lot of new approaches for old
problems because of the nature of distrbuted datacenters etc.
