talking to a max object outside max ?

Hello,

I am building an external application and i wonder how to communicate
with receivers objects in Max directly from it. I could use OSC SDK from
CNMAT and i will, for sure, but it'll be great if i could send things
such as typedmess() to a custom receiver object in Max. And it'll be
also great if it could go in the two directions. I'm sure it's possible
(this is two C++ apps...) but is it without the whole Max sources ?

best regards
