If you want to send as fast as Spread will allow, then you need to 
implement a flow control protocol between your applications.  Here is a 
pretty good discussion of flow control in Spread:

Spines is actively developed.  It is stable at version 2.2 right now. 
Check out www.spines.org for more details.

FYI, if you use UDP (multicast) in Spines I don't believe it performs 
*application* level flow control -- much like Spread.  Also, Spines 
doesn't exploit LAN broadcast or multicast capabilities, so within a LAN 
multicast is implemented as N point-to-point unicasts.  If your network is 
wide area, then Spines does a very good job of disseminating the 
multicast across the network.
