#2Volume silicon manufacture is planned
I highly doubt it. But if it's true, that would be the missing link for all open source hardware design.
It would also be nice if they gave some idea of the kind of performance or implementation they are considering.

#3I'm not familiar with the IP issues. Would it be possible to center open-source processor development around the ARM instruction set?
It looks like the privileged part of the RISC-V ISA is not finished yet. This is a great project, but it seems a long way off.

Historically, ARM really, really did not like unlicensed or open-source ARM processors. But times change, so I wouldn't be surprised to see them take some easy PR from openwashing at some point.

People are making volumes of Bitcoin ASICs for surprisingly small amounts of money, so it is possible. The question in my mind is who's going to be buying volume quantities of this chip and why.

A company like Silent Circle/Blackphone could buy a million or two in the future. Maybe some Raspberry Pi competitors, too.

That seems highly unlikely - unless we're talking about 3rd generation behind the latest tech chips. I could see them open source say the ARMv6 architecture in 3+ years, when ARMv8 has already taken off, and ARMv7 is in legacy mode. But meh.

I'm surprised they don't just use OpenRISC, there's already hardware shipping that uses ASIC implementations of that internally.

One of the team members was a co founder of the Raspberry pi.

#10That hardware implementation of RISC-V listed on their website is written in Scala (using Chisel). That's very cool. I want to see synthesis results.
