[Mycroft] Mycroft: [Installing] feedback from Steve LaRocque

Is there any way to detect through javascript whether a particular search plug-in (identified in any manner) is already installed?  I'd like to have an "install the plugin" link show up ONLY when the plugin isn't already installed.  Thanks all.
