At least this was the case when trying to run world compiled for Alpha on an i386 box. The reason is that many binary files and MD, and this needs to be dealt with. I wanted to start this project, but I still lack the necessary hardware (I only have a damn slow Alpha at the moment). I suspect more problems for different endianness architectures. Anyway, I briefly looked on the issue, and NetBSD has progressed a lot in this direction, so this should not be unsolvable. Once I get my faster Alpha or SPARC64 box, I will launch the project.
