I would like some input on the best way to copy protect my application. It is a client server app, the the licenses will be concurrent connections.
1,5,10,25, or unlimited.
Is there any source cose I can find to help me with this? It's a vb.net app.

I think the best way to do this is to compile the 4 kinds of the application seperately, then using remotesoft's Obfuscator or Protector to prevent cracking/decompiling. They are pretty expensive though...
Anyway here are the links:
