In a DCX mod based map adding the "homies" to other aircraft missile projectiles could work server sided.
Have you tried adding your Airwolf chopper to a DCX map and adding the homie code to the missiles ?
If so, you can make it a "map based" code that includes your Airwolf with the homie code and of course that would require a small patch file download for the client but well worth it to use the Airwolf in an aerial combat situation against fast flying jets. ( I would download it bro
)
As far as "how do the homies work", take a look in the DCX_F-15\Ai Objects.con and you will see how some AI codes associate them with vehicle path seeking referances.
I like the idea I think you're going with here and if you want to work on it together, meet me in one of my ventrilo voice com servers and we can figure out how to apply it ingame for what you have in mind.
