Before signing-up, it's worth reading their privacy policy and bearing in mind that they are a US-based company who will store your look-up requests on servers outside the UK, and are not bound by (and will not abide by) UK data protection laws. Interestingly, under the "mergers and acquisitions" section of their PP, they openly state that all personally identifiable data held on you would be transfered to any acquiring business, who may well not hold the same views on your privacy as the current openDNS ethos (Just imagine if a company like doubleclick bought opendns) . Since the speed improvements are marginal for many VM users, and you already have business with VM, who are accountable under UK data protection law, I would say the benefits don't really outweight the potential risks here.
