First of all, great informative site...
I'm looking to get the Dragon Board but I couple of quick questions:
1. In the code examples provided with the Dragon, do any demonstrate read/write access to the memory "space" (even if limited)? In other words, is there an example demonstrating indirect addressing?
2. Will I be entitled to download any future software developed for this board?

1. You can write to the memory space through the WDM driver that I provide with Dragon. In the example I made, the WDM driver receives an IOCTL request from the user application and does the access to memory space.
It should also be possible to "map" the memory space to user space, so that the application can do all the accesses, but Microsoft doesn't recommend it (and from what I read, Microsoft provides an example of use in the NT4 WDM SDK only).
2. Yes.
