Thanks for reminding me to actually *look*, rather than guess. I'm on
a 10Mbps hub.

fxp0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
        inet xxx.xxx.xx.x netmask 0xffffff80 broadcast xxx.xxx.xx.xxx
        inet6 fe80::203:47ff:fe63:6c94%fxp0 prefixlen 64 scopeid 0x1 
        ether 00:03:47:63:6c:94 
        media: autoselect (10baseT/UTP) status: active
        supported media: autoselect 100baseTX <full-duplex> 100baseTX 10baseT/UTP <full-duplex> 10baseT/UTP

And tcpdump(8) definitely captures unicast packets headed other
places. You put a box in a colo and you (or maybe it's just me)
naturally assume it's a fast switch, if not GigE, but I'm on a little
10Mbps hub. Couldn't tell you what make/model hub though -- the box is
3000 miles away. I've never even laid eyes on it. My friend who's
actually been there probably wouldn't know about such things.

Incidentally, here's the output of "netstat -bdI fxp0"
