You can assign config channels to activation keys; use the desired key for 
subnet X and you're flying.

On subscription/registration yes, there's a function doing this. Just make 
sure you enable config file management during deployment/kickstart (touch 
/etc/sysconfig/rhn/allowed-actions/all)
Changes can be pushed to the clients via workaround; just deploy a cron 
schedule with "rhncfg-client get" upon registration. Works fine, biggest 
drawback: you can not delete files (ensure => absent does not work)

Hard. You can send scripts to hosts upon actions via GUI. Limitations are 
huge, as variable to host binding is very limited (hiera, smartclass 
parameters, inheritance, etc... there's not enough comparable tools).

I could do this with Puppet via the notify metaparameter,

Know your feels. Migrate to katello/Satellite 6 and sell the move as 
"without alternatives"
