But we also would have to keep redundant configuration files... A pair of 
reader & writer always share a config file.

Here I can think of two approaches:

a) Keeping a config file for each process. This way is easy to know how many 
process to spawn from the number of config files. The config file should have 
to somewhat say if the process is a reader or a writer with a new parameter.

b) Keeping a config file for each "source". This would mean that a config 
file could spawn a "reader", a "writer" or both, which also would requiere 
new parameter, with three possible values. In the case of reader & writer 
process the same invocation could fork two times, so that the startup script 
didn't have to know about config settings...

I'd like to know what you think about these two approaches...

This is a remain from when XML or TXT files could be used for config. The 
check avoided that a XML file was feeded to the TXT module or the opposite. 
It's no longer necesary and I'll remove it.
