I am not dure I follow. Are you developing a native kdbus client
library for JS? 

Did I get this right, you have one bus connection per thread, but
possibly both a kdbus client and its service run from the server, and
you want broadcast msgs sent out from one to then also be matchable by
the other?

Can't you dispatch that locally? i.e. in addition to passing the msg
to kdbus also enqueue it locallly along the kdbus fd, or so?

But I am not sure I understand the problem fully...
