Ideas for a Viral Marketing Stategy

I am thinking of producing a short video as the basis of a viral marketing stategy for fields.

Josh Bernoff in his Viral Marketing blog entry at http://forrester.typepad.com/groundswell/2008/12/viral-marketing.html states:

"When it comes to viral video, you need to make sure

1) you create something people will spread and
2) that the video carries a payload -- a message about your product.

Fail on point 1 and your video won't spread. Fail on point 2 and you'll be a hit -- but it won't help your [product]. It's a very difficult balance."

Viral marketing is therefore a difficult balancing act but if successful could provide alot of publicity at low cost.

The above research has focussed my mind on producing an unusual video which may go viral. It will be a high risk strategy though as it could easily fall flat.
