You wouldn't need a dedicated channel for this, you can use the "data"
type message.

I've made a very quick implementation that takes this input

   data SERVERNAME.trends

   [file1.rrd]
   DS:set1:GAUGE:600:0:U 10
   DS:set2:DERIVE:600:0:U 20

   [file2.rrd]
   DS:anotherset1:COUNTER:600:0:U 12345

and then generates/updates the two RRD files. file1.rrd has
two datasets ("set1" and "set2") with the values "10" and "20",
and file2.rrd has one dataset "anotherset1" with the value "12345".

Would that fulfill your needs ?
