Well, syncronism is on the table, yes.

I suppose a master node could be defined, taking care of the  
semaphore management for the entire system.
This reminds me about Redis, couldn't that nice piece of SW be used?

Like this:

Init:
set sem1 1
set sem2 1
set sem3 1...

Use:
if( get sem1) decr sem1
get sem1
if (sem1 < 0 ) incr sem1
        wait/timeout
else...

and when finished:
incr sem1...

Maybe it's overkill...
