Nitro Steel,

CZ is supposed to introduce a .404 Jeffrey in 2005, and I think that someone is also suposed to begin manufacturing ammunition in that caliber also, but it has not been announced yet who is supposed to make it. So, in answer to you question, no, it is not currently available, but should be in the near future. I do not know what it will cost, but I am pretty sure that it will not be cheap.
