About the only option then is for the user to:
1) Accept that it's going to be weak.
2) Use server-side processing in his website to generate the license file
when the user requests the download. I'm certain this would not be hard
with asp.net. It would be harder with ASP as it would require a custom DLL
on the server and not many shared hosting providers are keen on installing
custom DLLs. Perhaps if we provided the custom DLL with source, many major
hosting providers would be willing to install the DLL. Otherwise, perhaps a
PHP solution could be created. I'm not too familiar with PHP so I don't
know how capable it is.
