Yazsoft has updated ShareTool (http://www.yazsoft.com/st/) for Mac OS X, which lets you access all of your Bonjour services from anywhere in the world, to version 2.0. With the new version you can now connect to multiple home/office networks simultaneously.
Formerly known as Rendezvous, Bonjour lets you create an instant network of computers and smart devices by getting them connected to each other. ShareTool automatically configures routers supporting NAT-PMP or UPnP. Remote services automatically appear in the Finder, iTunes, and other applications.
ShareTool 2.0 costs US$15 for a single-user license, $25 for a two-user license and $45 for a family pack (five licenses). Users that purchased ShareTool 1.x from April 13, 2010 – May 13, 2010 are entitled to a free 2.x upgrade.
