Kevin,  

This is a sample ldmd.conf configuration:

exec "ddplus -c -T 10 -P 9042 foo.bar.com"
exec "hds    -c -T 30 -P 9042 foo.bar.com"
exec "ids    -c -T 10 -P 9042 foo.bar.com"

The flags are from pqing, -c is the checksum flag and the -T is the time
out for a reconnection to start.  The feedtype, ie ddplus is a link to
pqing. One could use the feedtest program on the command line to test the
configuration instead of the above lines that would actually be in the
ldmd.conf.  Look at the man page on pqing for additional info.  I know
some of the flags are missing.
