OK, taken a look: it seems that the smallest Spartan3 usable is the
400Kgates. I don't need the ZPU now but good to know.

If you are looking for free soft core CPUs for use in an FPGA then look here:
http://opencores.org/projects
Look under processors for many CPU cores. They also have some
Eithernet controllers you'd need.

When you install the Altera tools, it automatically installs NIOS and gcc. I
assume there are no restrictions for private use, but you may have to send $ if
you make a commercial product. That remains to be checked.
