Serials Solutions has a press release today to announce the development of a product called Access Control Service, which is a hosted authentication and proxy service. Last year OCLC announced they were going to offer a hosted version of EZProxy, to go into production sometime this year, but I haven't heard anything more about it since then.
I supposed I can see a market for Access Control Service, but EZProxy has always proven to be one of the most robust pieces of software in our entire library arsenal, and a wonderful bargain to boot (though I don't know what OCLC is charging for new customers these days). I guess it's good to have competition in this area, if only to drive innovation, but ezproxy is one product I'm nothing but happy about 🙂
