I have a number of links to dump:
Dru Lavigne has found that Verio is offering BSD hosting (specifically, FreeBSD). She’s also got her own recent linkpile which mentions this odd thing, plus a Federico Biancuzzi BSD interview I think I missed.
KernelTrap has a DragonFly B-Tree summary similar to mine, plus a writeup on POHMELFS benchmark, that filesystem being mentioned on this site a few days back.
“FreeBSD – the unknown Giant” has changed domains to www.freebsdnews.net.
