Apple co-founder Steve Wozniak has lent support to online second-hand car sales company,

The company hopes to combine the demand for high-definition online video content with e-commerce applications.

Hotswap's website is at present a portal for buying and selling cars. Users can watch a video of the vehicle that's for sale while they make their purchasing decision.

Wozniak, who has signed-up to be a company advisor, told Reuters that he likes what Hotswap is doing, calling it "a definite step forward".

The company isn't just an e-commerce provider. It also holds patents on some forms of compression technology, which it claims can make webcam clips almost as good as high-definition TV on websites.

Hotswap even claims that fuzzy video made available through YouTube can be transformed by use of its technology.
