GHI provides a lot of value added on top of NETMF, see the GHI Profile http://www.ghielectronics.com/profile/
With that said, GHI would also like to sponsor those wanting to dig into the NETMF source codes. We started with FEZopen firmware and JTAG on FEZ Panda and now adding a complete DIY (do it yourself) FEZ, we call it FEZ Hacker. See image below.
The porting ebook details making ports for FEZ Panda and for FEZ Hacker. The free book is still in progress and provided as a gift to the NETMF community.
The book has all kind of information on FEZ Hacker.
We look forward to see the first FEZ Hacker made by the community. 2000 experience points will be added for the first member who makes one.
You also get GHI’s full support if you are interested in manufacturing this FEZ board commercially
