If you have 2.1 beta 15, we've made a beta version of our forthcoming Google Maps object available via the application. If you'd like to check it out, use the Sandvox > Discover Plug-ins... window to grab it. Just check the box and click Download & Install.
Please keep in mind this is a beta. It can't really do any harm, but it definitely has some rough edges. Please send any serious feedback to Karelia Support.
Just an update: there was a glitch on the server end where the Maps plug-in download was hidden for even 2.1 customers by mistake after a certain point in time. (One reason we're putting out the first, beta version through the "Discover" window, to make sure that's working properly as well.)
If you're interested in Maps, and you're running 2.1, please try again. We'd love to get feedback.
