I'm with those who said it's in the market, for various reasons. In pretty much all respects, it's about the numbers. Is there a big enough existing market/potential market for your product as it is? Are there borderline cases that might be sold on your product if they had a free trial? Is there a bigger market if you shift to another variant like the web-based alternatives penologist mentioned? What's your margin for any of this? Are you deterring people with a long domain/name? I realize I'm restating what other people said, but with many things, I think the math speaks for itself, or at least, it should. Run the numbers as ruthlessly and exactly as you can. Then make your decision based on that. If your heart is in this, maybe you can adapt it somehow so that the numbers are more promising. But let the numbers speak.
