that is one other problem, too. For example, i started to use Simili
when only the Win32 version was available. Fortunately the sources
are portable across other platforms, but compilation scripts are not.

it's useful, but i don't know if we can base everything on that.
i have never practiced FPGA so i can't speak.

true but compilation scripts are maybe a problem, particularly
when using a proprietary "integrated development suite" with specific
file formats and requirements. I have this kind of problem with
ncsim, which introduces several classes of files for different
purposes (note that ncsim is ideally not OS-dependent).
We don't have this problem with Vanilla and Simili.

As you noted before, the project must not be bound to an OS
or even a SW. but why bind us to a FPGA vendor, its tools and HW ?
it is also difficult to allow people to contribute if they can't access
the target HW and we can't force them to buy it.

i'm not a HURD expert and the OS-side is not definitively defined.
However, i think that if SRB is implemented, it should be ok,
as for ANY OS.
