In reply to Ale152:
Worth baring in mind that what you are basically asking is for UKC to give access to an expansive and valuable data set for free. While UKC doesn't have the same kind of big data as Facebook or Google or whatever, it all still falls into the same basket of valuable commodities that a company collects and can monetise. I would expect that you'd need to be willing to pay for access to that data unless there is some other good justification, like the research being wholly altruistic in nature.
Obviously I don't work for UKC so I've no idea what they would say, just pointing out that data has value and UKC is a private company that operates for profit (though obviously not purely profit driven and maybe not even primarily profit driven).
