Softrware Licensing / Registration component/framework? [closed]

Question

We use a home-grown Registration System for our software but I'd like to update it fixing a number of things including adding the ability to remotely activate/deactivate it (to facilitate Saas).

Feel free to suggest any good (in your opinion) VB6- compatible option. I can check out whether it meets our other criteria below.

Required Features:

• Activate multiple programs (Ok if it generates a separate code for each one)
• Works with VB6 and VB.net. A VB6-compatible DLL should be fine.
• Still supported (nice to have but not absolutely required
• Compatible with Windows 2000 through 7.

Nice-to-have features (but not required) * Work without internet access * Works through a firewall (this may be a tough one)

Any suggestions?

Check out ActiveX control: http://www.aztechsoft.com/timelock.htm

A little old school, but you should be able to wrap it in a .NET container using Interop.
