Ask HN: Anybody else running Raspberry Pis in production?

My startup is getting ready to release a product based on the Raspberry Pi. We're using it a controller for a remote sensor network that then uploads all the data to our central servers for analysis.

Is anybody else here using the Raspberry Pi in production?

If so, what kinds of issues have you had with it?

We know about the low write life of SD cards and are working to get around it, but we won't really know how well our product stands up until it's out in the field for months.

What are you using to develop and test them?

I'd love to discuss the challenges with anybody else working on a similar project.
