Recently came across remote access , remote control and VPN solutions. I found hosted solutions very effective in particular.
They offer security and are so much easy to use. I found RemotePC (http://www.ibackup.com/remote_access/
) and Gotomypc (http://www.gotomypc.com
) very productive. Specially RemotePC since it is cost effective also and they have a free trial version, so you can test it and then buy it if it suits your need.
