Now that there's a GPL version, it does mean other developers of Linux derivatives, or of Linux itself, could mine bits and pieces of the code, though, just like Akaros is doing. I agree a long-running GPL-licensed Plan9 fork isn't that likely, but now that there's even a one-time dump of the code under the GPL, it removes the legal barrier to kernel devs cherrypicking pieces of the Plan9 code and integrating them into patches. For example, the developers of Linux's v9fs implementation can now borrow code from Plan9's 9p implementation, if they choose.
