One thought on this; you really don't need to have SYNCs getting 
generated on non-origin nodes terribly often.

You might therefore set the -s and -t options to be much higher on nodes 
that aren't origins.

Where the defaults now are equivalent to -s10000 and -t60000, which 
overall force there to be a SYNC every 10 seconds, you might instead use 
-s600000 -t1200000, which would only force a SYNC every 10 minutes.

That would cut down on the amount of traffic at least somewhat.

I'm adding this to the documentation for slon.
