Do you know of any restrictions on using the "LinkedIn" logo as part of the "contact references" you can give to clients?
LinkedIn permits its members, third party developers, partners and the media ("you") to use its name, trademarks, logos, web pages, screenshots and other brand features (the LinkedIn "Brand Features", "Marks" or "logos") only in limited circumstances and as specified in these Guidelines. http://developer.linkedin.com/docs/DOC-1101#general-use
