Interesting, I didn't know online HCI grad programs even existed.
On a related note, I do wish that a premier design school (e.g. RISD, Art Center, SVA, New School, CMU) would step up and address the need for online / part-time IxD "executive MFA" program for practitioners, along the executive MBA model with a mix of online learning and on campus sessions. Forgive me if I've overlooked an existing program, but it seems (just based on this discussion list) that there is a significant demand for this option, particularly with the current economic pressures.
