Looks like MIT is also planning to kick off online-courses with MITx — in the style of stanford’s Coursera — the first one is 6.002x (Circuits and Electronics) and is said to start next month. Like the Stanford courses there will be some electronic certificate of accomplishment.
More info about MITx on http://mitx.mit.edu/.
There’s also a new (to me) website with information about all these courses: http://www.class-central.com/
I first read about this from here.
