I've started the process of getting some of the modules (the ones where the code is not site or business specific) released to CPAN (red tape) but can't promise or predict if those will ever be released.
I know the feeling, red tape can be seriously annoying (not to mention soul sucking). Fortunately my current boss sees the value in open sourcing modules to CPAN, especially since we utilize CPAN so heavily ourselves. If you utilize CPAN at your work as well, you might try that argument as well. After all, giving back the community only helps to strengthen it, and that helps everyone involed including your boss/job/coworkers/etc.
