>> pps: can redirfs be used for channel bonding, i wonder?

> Excuse my ignorance, what're you thinking about?

i didn't know what it is until recently either.  on many of today's
servers (pretty much all AMD64 boxes I've seen) you get not one but
two network interfaces.  channel bonding allows you to use both of
them for sending data as if they are one.  some people report almost
double the bandwidth, but i've only seen 1.2Gbps with netpipe on
untuned broadcom GigEs.

for channel bonding you need either all machines on the subnet to be
talking it, or the router's support.  the linux module is called
'bonding', there's a reasonable explanation in the kernel source
tree's Documentation/.

i was thinking that redirfs could be used to send packets over two
alternating /net interfaces.  a level of indirection above /net may be
na=C3=AFve and slow, but it don't seem all that hard to implement, maybe.
