Several points:

1. Charging money for something so trivial is not only foolish (my opinion) but won't bring much profit at all at the same time restricting the usage of something that is made to help people (logical analysis).
2. Open source forever.
3. And you needed .NET to accomplish something of this level why...?
4. The app'll be cracked and freely distributed on the net (granted not too widely spread for obvious reasons) before you can say "Posix".
5. Down with MS.

That is all...

P.S. Intent and will power are the best "utilities" to achieve anything; let alone something so deeply related with the subconscious as lucid dreaming.
