there are a bunch of carpool apps in the google play store, but they're not quite what I'm looking for.  they help arrange ad-hoc trips.  they use gps and such to compute how much each participant owes.  they don't generally work across platforms (I have iOS and Android participants)

in my carpool, participants don't pay each other; they just take turns driving.  that sounds pretty simple, but schedules being what they are, participants miss days, and often the driver is determined only by last-minute texting.

so a few things I'd look for in an app are:
 - a carpool consists of a route, a schedule, and two or more drivers.
 - counting rides given vs. rides received.  the next driver for a carpool will be the one with the lowest ratio.
 - calendar.  at a glance, you can see who will be driving on which day.
 - reminders.  the app notifies (possibly just texts) you when it's your turn.
 - confirmation.  you can tell the app that you're confirmed-in, or out.

We need an API for the module sequence footer (the navigation at the bottom of an assignment, discussion, etc., that links to the previous and next items in the course module sequence).

How should we specify the object we want sequence information for?

The non-API endpoint takes an asset tag. An API call like this would look something like:

(A) GET /api/v1/courses/123/module_sequence/assignment_456

Or maybe we would rather see:
