well, if you're not going to add any rules to OUTPUT, then--yeah, leave
it at ACCEPT.  the OUTPUT policy as ACCEPT or DROP is really more of an
idealogical debate than anything else.  personally, i set mine to DROP
and only allow the traffic that is absolutely necessary to save me from
myself (i.e. don't tempt the fw admin to use the fw as a shell
account).  things i deem necessary to allow out:

  DNS
  NTP
  FTP/HTTP to update server IP's
  ICMP

this is all politic, i don't intend any decree by the statements made
here.
