Are you going to make the source available? Very few developers are willing depend on a library whose source is not available. If the code is good you should be able to charge for the source under one of the various licenses available. Pirated source code is something that can't be avoided but it is way better than something which will not be used if source is not available. That is something that Delphi component developers learned. Without source no one will be interested in your code because they will be left with a product they cannot fix if there are bugs and you are not ready, willing or able to fix them.
