I got the Ircam library.
As I wrote in Northernsounds it's a nice palette, and even the mainstream composer can succesfully blend it with any existing library and/or virtual instrument, VSL included, whenever he or she needs some dirty, grotesque, sarcastic, unusual or rough "contemporary" mood: with the Ircam lib you get tons of really uncommon and flawlessly recorded sounds, their demos give an exact idea of how it sounds right out-of-the-box and the library has nothing to do with VSL or EW. At the present time, it's not a VSL competitor: it's a (serious) contemporary solo instruments library, not an orchestral-FX one.
Their UVI player works, but, to be honest, it's not exactly a state-of-the-art piece of software. I guess (and hope) it will be improved...
