Oh, and how about a posting on the .LRN frontpage encouraging students to apply for this? After all they can apply for an "Other" organization, which could be .LRN after all (see
http://www.winehq.org/ for an example of what I mean).
And while we are at it:
If you are a student and are interested in OpenACS and .LRN apply today at http://code.google.com/soc_application.html choosing and describing either your own project idea (using the "Other" organisation field until .LRN makes it into the official list) or take one from the list provided above.
