 bundle of host callback function pointers too?

 The host "object" will have functions to do stuff.


Maybe this should be done right off.  Presumably, the host is already
initialized.  The plugin might want to make some host queries during
its own init phase.

That's what I was thinking. It seems like you'd want to pass the host function ptrs to the factory just once upon first use, maybe something like factory::init( theHostCallbackPtrs ). Then the factory can get them to all plugs at instantiation time.
