I do use RRDs to connect to rrdcached via unix socket (not TCP) and
send RRDs::update.

See below:

  RRDs::update("$rrd", "--daemon", "$rrdcached_address", "$record");
  my $ERR=RRDs::error;

  rrd - is my rrd file on disk (For unix sockets Im really using 
   abolsute paths to update)

  rrdcached_address - is my rrdcached socket address
  record - is the record I send to be updated

Works fine. Im testing this setup with over 100 rrds at the moment.

See above.
