Jim is right, the idea of implementing a mid-level interface that would be at just the right place of device-independence always horrified me sufficiently to stay well away from it. But it sounds like a agreat idea. :) -- Maurice LeBrun ------------------------------------------------------------------------------ Dive into the World of Parallel Programming The Go Parallel Website, sponsored by Intel and developed in partnership with Slashdot Media, is your hub for all things parallel software development, from weekly thought leadership blogs to news, videos, case studies, tutorials and more.
