David I am curious as to why you think OpenBD (or any other high level
system) isn't up to the job.
Amazon DynamoDB is more than just a bigger SimpleDB. Size of your
dataset has very little to do it. The key difference with DynamoDB and
SimpleDB is that for any large cross-document queries you wish to do,
you really have to jump into MapReduce algorithms to get any sort of
performance from it. The other key advantage over SimpleDB is a
guaranteed level of service, that is what you are paying for. SimpleDB
isn't the most reliable at times, with API calls timing out and
disappearing at times.
If however you are managing user-profiles for example, where you will
for the 90% of the time never be querying across documents then DynamoDB
is going to be your fellow, and OpenBD is a perfectly client tool for
that job.

I have worked with it for a few days... and if you really need the
scalability and size of dynamoDB (it only has advantages if you expect
your data sets to grow bigger than 10 gb and you're willing to create
all your indexes yourself) than I doubt openBD or any high level
system is up for the job. Either way, I really advise you to recheck
whether you're sure simpleDB isn't more appropriate for the job than
dynamoDB (we chose initially for dynamoDB because it seemed to be the
'next' version of simpleDB, but it's an entirely different product we
realized over time). If you're sure you want to use dynamoDB I might
have a half working java cfscript component lying around.
