The easy thing to do is to just define a bunch of init scripts in a single service with the IP resource. Problem is, of course, that if one script returns non-zero, all resources in the service are stopped and restarted.

In CVS for 5.1, you can add a special attribute to the tags in
<script name="this_app" file="/bin/this_app"
This means that a failure of this script will cause a stop/start of that
script without stop/start of the rest of the siblings in the service
