For those who are interested in Plan9, you may be interested in checking out the following:<p>* Plan9port (Plan 9 from User Space) ports a number of the Plan9 programs to Linux: <a href="http://swtch.com/plan9port/" rel="nofollow">http://swtch.com/plan9port/</a><p>* wmii (<a href="http://en.wikipedia.org/wiki/Wmii" rel="nofollow">http://en.wikipedia.org/wiki/Wmii</a>) is a tiling window manager that allows configuration through a Plan9-like filesystem. A number of people I know (myself included) were first introduced to the power of Plan 9 through wmii's extensive configurability.<p>* Go (the language) has borrowed a number of elements from Plan 9. One of the two main compilers (gc) traces its origin in the plan9 toolchain.<p>* Acme/Wily (the text editor). I'll have to confess that I never took to this much (as a Vim user), but give it a shot.
