A couple months back, Joel poked around with the Roku Netflix Player. He thought it was okay, with a great interface that passes the "I'd let Brownlee use this" test. Since I didn't see that comment until now, I hope your eyeballs rot, Joel. Idiot-proof or not, though, Joel was ultimately ambivalent about the Roku:" If and when the Roku box serves up other streaming services it'll be a nice little node to stick on your TV to slurp up some free(ish) web media. Until then, it's probably for Netflix.com die-hards only."
If you pulled the trigger on that enthusiastic recommendation, doubleplus good news! Forbes is reporting that Roku will soon be rolling out an update to allow their player to stream from other select online video services. And even better? They've just released the GPL code for the plucky Netflix player. Hopefully, that means that even if Roku doesn't support your preferred brand of digital Slurpee, plucky hackers will figure it out for you.
