All,
Just wanted to toss this out there FYI. I've been working on a project for a good long while that automates Ae renders via an app and on the web. I've been involved both in the template design (only one simple template right now, more in the pipeline) and the back-end implementation (which has been significant). It's been a satisfying mix of left-and-right brain application :)
Here's the link for the app (iOS only, Android coming) if you'd like to kick the tires. Bugs can be reported to me directly, and favourable reviews in the app store would, of course, be appreciated :)
