I'm wondering if the shareware concept is dead nowadays.

Like most developers, I've built up quite a collection of self-made tools and code libraries that help me to be productive.

Some examples to give you an idea of the type of thing I'm talking about:

• A self-learning program that renames and orders all my mp3 files and adds information to the id3 tags;
• A Delphi component that wraps the Google Maps API;
• A text-to-singing-voice converter for musical purposes;
• A program to control a music synthesizer;
• A Gps-log <-> KML <-> ESRI-shapefile converter;

I've got one of these already freely downloadable on my website, and on average it gets downloaded about a 150 times per month. Let's say I'd start charging 15 euro's for it; would there actually be people who buy it? How many? What would it depend on?

If I could get some money for some of these, I'd finish them up a bit and put them online, but without that, I probably won't bother. Maintaining a SourceForge project is not very rewarding by itself.

Is there anyone who is making money with shareware? How much? Any tips?
