AXD 301 uses run_erl, and has done so for many years.
Combining run_erl and heart is no problem at all. The
environment variable $HEART_COMMAND specifies a script
to be run in case the erlang node dies. This script can
use run_erl to start the erlang node.

One issue with run_erl/to_erl is that you get into trouble
if two users use to_erl simultaneously towards the same
erlang node. Nothing prevents this from happening, but the
results will be confusing (run_erl sends all output to the
same named pipe and the two to_erl processes compete for
read access.)
