Hi

This PDF tutorial may help you:

TeamViewer, http://www.teamviewer.com/en/index.aspx, is free for non-commercial use. It is excellent.

VPNs are slower, but more secure. No more to it than that.

NeoRouter is a VPN, its a different use. VPNs can be used to connect remote locations as if they were on the same network, securely. This is one use case. The other is to hide your identity, by making use of someone else’s servers who will not divulge your information. They’re exactly the same technology, but different applications – that’s all.

I can’t see any advatage to making remote desktop thinking its a lan – youre already dialling into the remote network anyway, and it IS on the lan at the remote location. However, a VPN would ensure the connection is secure, that’s all. It may be a requirement in many companies.
