Rhino Licensing questions

[Drex]

Hi.
I'm new to the licensing systems and I was looking for this project to
licensing my WebApplication.
And now I have a couple of questions:

- I'd like to have the ability to lock the license to a single
machine.
To store this value in the license file, should I use the custom
dictionary provided by the Generate method
or it's better to make some custom overload to LicenseGenerator?

- When I need to validate my license file, I need my public key.
Can I store this key directly in my license file or it's better to
have it saved somewhere else?
There may be security issues?

Of course, I need a custom validator on both cases...

I know that the project is open-source and I can make my own changes,
but I'd like to hear some opinion.

Thanks

Another question:
When I create the license, the file it's in plain xml with signature.
Some users can look at the structure of the file, create his own copy with his new key/pair, than replace the public key.
Replace the public key is really easy if it's in a separate file and a little bit difficult if it's hardcoded in an assembly.

Is there a way to make secure this files?

I really appreciated any kind of help.

Thanks
