I know.  nanobsd mounts all of its filesystems read-only as well.  See:

This still means you need to reboot, but OK.  I didn't try the PXE thing
when I was doing the filtered bridging stuff and I found this extremely
difficult to work with (on the other hand, expensive edit-compile-debug
cycles forced me to write better code).

Absolutely.  I said that this wasn't much of a test.  :-)

One old datapoint:  I measured about 25 Mbps between a couple of my
machines going through the bridge plus a 100 Mbps switch (endhosts were
400 MHz P-II and 1 GHz P-III, both RELENG_5; bridge was a net4801
running HEAD from about August).  It was 86 Mbps without the bridge.  I
did not try any particular optimizations such as interface polling but I
did disable INVARIANTS and WITNESS.

I haven't had a chance to repeat this experiment with 6.0-STABLE but I
know there was some work in the network stack since I did this
