Are there institutions using Dragonfly from http://www.dragonfly.com ?
If so, I would be interested in hearing if you are shaping this
application's bandwidth or have taken any other measures to throttle it down
and control the IP addresses it talks to.

One of our department has purchased the software and it seems to be very
bandwidth thirsty.  In addition the P2P model they are using seems not to
handle RFC1918 IP addresses so our internal sensors are triggering when
Dragonfly tries to connect to a peer over a private IP.

Our athletics department is using it. We keep it limited at all times
except for an agreed upon
span of time from Saturday night into Sunday morning.  We use the
Packetshaper scheduled
commands to turn the limits on and off.  It is extremely demanding and
before we enforced
the limit, it caused degradation of service for everyone even when it
was not supposed to be
in use.
