Do video CVs really work?

So i've been reading a lot about video CVs being the next big thing. I'm not sure this is true. Or certainly, i don't think it will be true for the English audiences for a very long time to come.

Maybe it's down to the Great British personality but being natural and comfortable talking to camera is a strange and difficult experience for most. Start talking about your strengths and all the good interview speak normally saved for 1-2-1 sessions with the interviewer and things will probably get harder. Talking to an interviewer in the flesh is more natural and candidates will be able to get themselves across better.

So, will a video CV help you get an interview? No - not least because most recruiters are not ready to receive and view video CVs. A classic example of it not working is here.

Will the Great British public be producing their own video CVs? You tell me.
Do you have a video CV?
What has the reaction been?
Has it helped you get an interview / job offer?
