Trialware and E-commerce software wrappers.

[pdablue]

Hi,

Does anyone know of any good Trialware or E-commerce
wrappers that can be used to wrap an .EXE file for distribution
over the Internet?

For the Desktop or the Device?

If you wanted to write a program in B4PPC that you would
like to sell over the Internet what is a good way to get
started?
