Perhaps some kind of a hardware solution can be used. I.e. attaching a pci with memory and addressing it's 64gb memory either directly (if you have 64 bit bus) or in two phases. It can also be any RAM space size you choose, but it will cost you (each additional bit doubles your costs :) ).
So what you are advocating is an expensive RAM disk ? The process limit is still there. 32 bit cpu registers cannot easily manipulate more than 3 GB of data. Any index etc must be limited to this size. The runtime for accessing a 'ramdisk' will explode wrt running a single large process.
