Question for my personal intereset: why do you want to do it?

Modifing ser.cfg will never result in just one process, because their is 
allways a timer process.

It hardly depends on the modules you use. But usrloc for example will not work 
without shared memory. And i think also tm will not work without shared 
memory.
So if do not use any module which needs shared mem you will probably end up 
with a stateless SIP proxy with not many features.

Conclusion: it could theoreticly be possible to use Ser without shared mem 
with probably a lot code changes. Allthough i do not understand the intention 
for this goal and the result would be unsatisfactoy in terms of performance, 
features etc.
