Perhaps you could contrive to compile all of the services you need into 
the same (statically linked) executable. That way the linker could 
discard anything you don't need.

Is all this stripped? You don't need the libCOS... stuff. 
_omniidlmodule is only required for building applications, not for 
using them.

You are right. The Event Service doesn't need DynAny (nor does 
omniEvents).

*omniEvents* uses the DII - that's an implementation detail rather than 
a requirement of the spec.
