# first create a hubfs on a hub server machine and make some extra hubfiles
gridterm: hub -b aes
creating hubfs /srv/aes
gridterm: mount -c /srv/aes /n/aes
gridterm: touch /n/aes/encin
gridterm: touch /n/aes/encout
gridterm: touch /n/aes/decout

# now on another machine we mount the hubfs and have this machine do encryption
cpu -h gridtwo
import -a gridterm /srv
mount -c /srv/aes /n/aes
hub aes g2
g2% auth/aescbc -i -e </n/aes/encin >>/n/aes/encout <[3] cryptkey

# on another machine we mount the hubfs and read the encrypted data and decrypt it
cpu -h gridfront
import -a gridterm /srv
mount -c /srv/aes /n/aes
hub aes gfront
gfront% auth/aescbc -i -d </n/aes/encout >>/n/aes/decout <[3] cryptkey

# back on the hubfs host we will start bursts of data flowing into the hubfs
gridterm:
bind /n/aes/encin /x
c=0
while(sleep 10){
	cat /lib/words >>/x
	echo $c
	c=`{echo $c' + 1' |hoc}
}

# and on the fourth machine we mount the hubfs and read the decrypted stream
helix:
import -a gridterm /srv
mount /srv/aes /n/aes
cat /n/aes/decout


# gridterm > g2 encrypt > gfront decrypt > helix read
# any node can host hubfs and any code and read/write to any hub file descriptor
