I think that depends on how you implement your network. 

If you blindly dial from one side to the other, then no because you are
transfering control to the remote machine to take control. 

If you use switch statements, you effectively share your dialplan with
the remote machines and they then can query if you have matches. You
could implement a new application that looked for a dialplan match
without doing a real dial. Then you could then implement your dialplans
with a free context and a non-free context which are linked to your
local dialplans via switch statements. You can then testdial a extention
in your free context to see if it comes back with a match, then test
dial using the non-free context.

I think you will want to look at pbx_find_extension in pbx.c
