I think the answer, as usual, is: "It depends."  It's not a silver
bullet for all problems, but it would probably help in some cases.  I
would actually think Server could use this more than Workstation, as
the article points out that wireless networking has a number of other
issues to consider.  I've added Neil on CC, who's probably much more
equipped to weigh in on this than either of us.

In any case, if this change is done it should be done in the
initscripts package.  It's a runtime tunable and we don't need to be
patching the kernel to change the default.
