Interesting for people still working with Frontier: the kernel is likely to become open source. As a result, this could mean that some of the uglier problems (e.g. the terribly poor performance under OS X) could be solved. After all, Frontier is still pretty cool in many corners even today (the OO database with outliner basis, for example, is something that doesn't exist in this form elsewhere - even if some people grumble that you don't actually need this particular combination).
At Second p0st you'll find the original article.
