Are the modules you're thinking of heavily shared/shaped by the needs of others? I think it's fair to say that there are more influences than just communication patterns on the design of software. For instance, there's can be a different set of concerns/pressures on developers of open source libraries than on time-sensitive and closely coordinated projects within a company.
