He has given me permission to include them here. There are now. VSIA has produced about 8 specs, and will have about 12 or so released by year end. There is no de facto competitive marketplace where you can buy and sell similar virtual components. Currently there is no official market, partly because there are no SoC standards, and partly because the ownership of Intellectual Property, IP, is fuzzy.
Problems are with long time to develop contracts, and long time thru legal.
Also indemnification from infringement. Large companies can cross license each other or agree to not sue each other, since they have big IP banks. IP protection is separate problem. VSIA is working on emerging technologies to protect. I would encourage you to take a peek.
