Software protection and license management

Question

I have following requirements for selecting a license product for my software

1. .Net based
2. License manager - Should be able to view and manage the customers interactively, automatically,e-commerce is not mandatory.
3. Good Customer support, examples and available source codes
4. I may need to update the license monthly and exciting users should be able to get those from license server automatically (mandatory requirement, we control the customers like this)
5. And Most importantly the price for my requirements

Based on these requirements I have following options

1. Software Key (http://www.softwarekey.com/protection-plus/5/)
2. CryptoLicensing For .Net(http://www.ssware.com/cryptolicensing/features_net.htm)
3. EZIRIZ(http://www.eziriz.com/)
4. LicenseSpot (http://www.licensespot.com/)
5. Eleckey 2.0 Internet Plus (http://www.sciensoft.com/products/eleckey/comparison.html)

Do you have any views or any more suggestions on this? What would you suggest?

Edit

I found this link for CryptoLicensing , this one for Eleckey 2.0 and this one for manco.net. Any comments for other products?

Answer 1

According to my requirement (hosted web server) and experience,there are two choices. one is Software Key and the other one is LicenseSpot. Both have their own advantages. Software Key is feature rich and instant customer support. LicenseSpot is simple and price also less
