Here's on for crowd. I am using and loving the custom variables and have run
into an interesting idea. I have a host, a firewall, that has multiple
interfaces and multiple address per interface. I also have a hostgroup that
contains basic host checks for the os type. In the host group object file I
have a check for the first interface using a custom variable. What I would
like to do is have the hostgroup definition check all enumerated interface on
that host. I figure it can currently be done two ways:

1) Write a wrapper to grab all the environment vars for the interfaces and
loop through them. This would be a single service definition.
2) Define a service for each interface. ( Currently being done in the host
object file )

What I an wondering is would there be a way to dynamically generate the
service definitions for each interface?

Below are sanitized versions of my object files.

## begin host file billy.cfg
define host {
use all-hosts
