Figured out my issue... I wasn't being patient enough after calling the service start before checking to see if port 4445 was bound yet.
root@host:/etc/rc.d/init.d $ netstat -lnp | grep 444
root@host:/etc/rc.d/init.d $ service fop2 start
Starting Flash Operator Panel 2: daemon /usr/local/fop2/fop2_server -d -i venet0 <--- added this echo for debug
[ OK ]
root@host:/etc/rc.d/init.d $ netstat -lnp | grep 444 <--- ~500ms between each
root@host:/etc/rc.d/init.d $ netstat -lnp | grep 444

For reference, I'm using the latest as of 12/22/2012. I believe it's 2.26
The distro is centos. It's a PIAF purple install.
