One of the projects that has captured my attention lately is getting a test server with WeBWork up and running for the math faculty at my college.
https://openwebwork.org/
This is an open source project designed to provide a platform for "online math homework" (think MyMathLab).
We have the test up and running so the faculty can explore it, and will be moving to development in the spring, with a target of production for the fall semester.
I'd be glad to hear advice/ recommendations from folks who have rolled this out.
