[Jian Chen]

I am considering writing some shareware in python. I got some
questions about it:

1. Is there any good shareware in python? where can I find?

2. Is python suitable to write shareware? as I konw, it is not easy to
pack python programs in standlone exe program? is there any tools for
the packing & installing of python software?

3. How can I lock/secure my python shareware?

any suggestion? TIA ;)
