Architectures we want to port MOOSE on:
- The i386 architecture, because it is common and cheap.
- The ARM architecture, because it is powerful and cheap.
- The PowerPC architecture, because it is even more powerful, and will
 hopefully become cheap and the new standard.

And perhaps:
- The Alpha architecture because it's powerful.
- The SPARC architecture because it's widespread on workstations.
- The M68K architecture because it is somehow widespread.
- Anything someone is willing to write it for (including MIPS,VAX,HP/PA,etc)
- MuP21 OK processor because it's cheap and powerful.
