Spread can pack messages.  I would agree with you though.  I would wager 
that your packing method would be more efficient than Spread's because 
Spread can't make the blanket assumption that all the messages are going 
to the same place.  The packet headers on Spread messages are big when 
you look at message packing.

There are many applications where it makes good sense to increase those 
"hard limits" in Spread considerably.  There are a lot parameters that 
can be tweaked and tuned to make it run better on LANs vs. WANs and more 
appropriately "fit" the needs of your application.  All of these require 
a recompile of the Spread daemon.
