Firsts in NetBSD

[Swift Griggs <swiftgriggs%gmail.com@localhost>]

I'm writing some documentation for a class I'm teaching soon at my job. 
One section covers various BSD's (each separate) contribution to features 
in the collective endowment of Unix variants out there.

Here are the things I believe NetBSD was first at doing. Can anyone else 
think of ones that'd be worthy of note to a group of up-and-coming Unix 
geeks ?

* First with a USB stack (beat Linux didn't it?)
* First with TCP Auto tuning (Linux's autotune based on NetBSD's strategy)
* First with Free ports to Alpha, HPPA, and MIPS (true?)

I know there are more NetBSD "first to do XYZ". Does anyone care to 
correct those three or give me some more? Thanks in advance, friends.
