One of the new features in 4.1b2 is support for the "mactracker://" URI scheme. With this scheme you can create a link to have Mactracker take you to a specific info window from another application like Safari, iChat, or your company's service/inventory/client database.
Simply open an info window and select "Show Model Hyperlink" from the "Edit" menu. In the "Link" window that appears you have two choices for creating a link; "Address only" and "Address with HTML source". The latter is likely best for use on web pages and forum posts.
An example of "Address only":
An example of posting the "Address with HTML source" link:

Mactracker 4.0 (and later) also supports receiving AppleEvents from applications like FileMaker Pro. I have included an example within Mactracker's application package.
