open source or freeware

Say you have put in a lot of effort in developing a pl/sql package that helps you in your job.
You think it does a reasonable decent job and you are thinking about releasing it to the rest of the oracle community.
However you are affraid to lose control over your application. I mean, you have put so much work in it, can you then just give it out hand or would you still want to control it?

Of course you could wrap it and distribute it as freeware, but who would install a wrapped package from the internet into their production databases?
You could try to work arround that by splitting of part of the package needing a higher level of privileges into separate packages which are left unwrapped and can be installed into a different schema. But would this be sufficient?

You would also be the sole responsible for support and bug fixing as you are the only one with access to the code. That is the only one, excluding those who have access to an unwrapper, with which they can revert your code back into its original state (including variable names).

Another option would be to share the source code, but what would happen then? Probably people would start modifying your code.
Is this a bad thing? Maybe that depends if they afterwards would start bothering you with questions as “why it doesn’t work” or not.
Would you allow people to send in their modifications or would you only maintain your own version? Could these modified “versions” then still use the same name as your original package or not?

Then there is the question of licensing. Would you just publish the code, or would you put a licensing on it? If so, which one?

Many questions and few answers.
So tell me, what would you do and how would you do it?
