I thought of some additional ideas. What do you think?

- Invitations

- A "materials needed" list for each class

- A public forum for general subject discussion

- A calendar

- Conferencing (with voice, video, images, chat)

- Buy books or supplies if needed

- For learning languages, there could be a service to chat with a fluent speaker

- To make tests, you can use something like Wufoo to make forms for tests

- Background theme for classes

- Progress charts

- Grade checker

- Mobile apps

- OpenID/other logins

- Citation helper

- Look up quotes and verses

- For whiteboard, maybe something with HTML5 canvas

- Group mailing list

Wow, thanks for the list. That's more features than I have time to add though. For some of the bigger items like the whiteboard, I'm hoping people can use other services in the mean time. Some of those items are being worked on now though.
