In my opinion: Yes, you should.

Not because of my DreamRemote application. No, because of your security. It's always better to connect your PC behind a NAT Firewall to the Internet. Connect it directly is in many cases riskful. Especially if you are using Windows. (I don't know what you're using, just guessed)

No problem at all. I hope at some point in the future I will figure out how to handle a password protected connection. But I'm afraid of the security risk. Should I store the password? How to scramble? When someone has to enter it every time, is my application still useful? And how to ensure that there is really a Dreambox behind the IP Adress I'm sending the password to get access?
Hmm... in my opinion to many unanswered questions for myself. I want to provide a secure application.

But if you still like my Application, please vote for it at the coding competition.
