Hmm, I was just watching the news on TV and they said that MS had to release some of their source code - I thought that was a tad unfair but reading the above link it appears they just need to define and document the protocols that work group servers use to communicate (someone needs to define a work group and a domain to the EC) - the actual code will remain closed, which I think is pretty fair.

I think this will result in a lot of 4 rate applications popping up that do not work well with a work group/domain infrastructure, as there will no doubt be a race to produce these app's and get it on to the market 1st.......I personally will still lean toward an MS product for an MS domain. However a good thing that will almost certainly come from it is that providing some decent and realistically competitive software emerges, then MS will have to drop their prices to compete.....and that is most defiantly not a bad thing...
