Forcing a check on a Desginated Slave from cmd.cgi?

All:


In the el-generic Master w/NSCA distributed configuration, has anyone
developed a hack to have cmd.cgi pass a SCHEDULE_FORCED_HOST_CHECK or
SCHEDULE_FORCED_SVC_CHECK received by the master instance, onto a
designated slave?

We have a config where our slaves are in remote facilities and the
master can only rely on passive checks -- attempting to force an active
check on the master is a no-go due to network ACLs and other
limitations.

It would be nice to only need one web interface on the master NSCA
receiver.

The problem is two-fold (and this gets into the whole inter-component
architecture discussion) -- 

1) Even with a cmd.cgi hack, there is no native meta-data within Nagios
   to associate a host/service with a designated slave.

2) There is no clean communications channel other than a shell script
   wrapper (ssh and keys, etc. that stdout's to the slave's nagios.cmd
   -- this could get ugly...fast)
