set up auto-announce of samba server on osx lion (since finder / pathfinder don't see samba servers by default atm)

osx-lion-samba-server-announce.txt

from: http://macw.us/sek9nV 
(for more information on creating launch daemons / agents, go to http://j.mp/uYtpsJ )

create a file in ~/Library/LaunchAgents
named something like:
com.yourdomain.smb_server.domain_announce.plist

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
  <dict>
    <key>Disabled</key>
      <false/>
    <key>Label</key>
      <string>com.yourdomain.smb_server.domain_announce</string>
    <key>KeepAlive</key>
      <true/>
    <key>ProgramArguments</key>
      <array>
        <string>/usr/bin/dns-sd</string>
        <string>-P</string>
        <string>yourmachine</string>
        <string>_smb._tcp.</string>
        <string>.</string>
        <string>445</string>
        <string>192.168.1.33</string>
        <string>0.0.0.0</string>
      </array>
  </dict>
</plist>

change the "yourdomain", "yourmachine" and 192.168.1.33 appropriately (yourdomain / yourmachine are somewhat arbitrary -- the yourmachine will show up in finder, yourdomain I think is mostly just descriptive, and the ip address should be the ip of the samba server)

the execute
launchctl load ~/Library/LaunchAgents/com.yourdomain.smb_server.domain_announce.plist
or reboot your machine (it'll stay running)
