Normal DMA requests on the Cell happen between the SPUs and the PPU. However, I have read that it is possible to set up DMA directly between SPUs. Anyone have any idea how this is accomplished?

Have a look at spe_get_ls(). This will help you to setup a list of effective addresses that you can use to transfer data between local stores. You may need some management to map spe identifiers to physical SPUs.
