The first place to visit is the tour. The next thing to look at is the help center article What topics can I ask about here?, which includes in the list of on-topic subjects:
- personal and home computer networking
The question was migrated from Theoretical Computer Science to Server Faultto Server Fault, where it was closed as being not about business systems. Evidently, they consider it a home networking question, and such questions are on-topic here.
However, the poster definitely needs to narrow down the scope of the question before asking it here. We don't deal with legal issues (since they vary from jurisdiction to jurisdiction, and aren't really about computing). Also, it's much better to ask how to do something than how challenging something would be. To help the poster, we'd need to see what was already tried and a specific technical goal.
