I discussed this with the author. The problem is not the overhead of the IPC, 
it's the service you want to communicate with. While most services on Linux 
use D-Bus, we'll have to use it too to talk to them. Splitting up won't help 
much.

libsharedmem doesn't solve the major problem that people complain about in D-
Bus, which is the central server that does the relays and includes far too 
much validation on incoming messages.

But it is a nice project and we could certainly use it in other places.
