ShareTool is the smart and secure way to take your home or office network with you wherever you go. So smart, in fact, that we've been named a Mac Gem and an Apple Staff Pick.
ShareTool is a fast, extremely secure, and magical way to remain connected to your home or office network(s) no matter where you are physically. While connected with ShareTool, many shared (Bonjour-enabled) services on your remote home or office network automatically appear in your Finder, iTunes, iPhoto, and tons of other applications (just as they would if you were physically located at that network).

ShareTool automatically provides Bonjour over VPN connections as well. No messy configuration required. In addition, you can run ShareTool as a Mac OS X service via a background daemon. This means you don't actually need to be logged in as a user to share your network. Further, ShareTool 2 supports connecting to multiple networks at the same time! There no longer is a limit to the number of networks you can be connected to simultaneously.
