Good day list,
I've put together a few JQuery components for use with Magritte descriptions that are working quite well for me. I posted them in the Magritte2-AddOns repository.
Currently datepicker, timepickr and autocompleter are working.
The autocompleter applies to a MAToOneRelationDescription and adds an updating script that allows you to render information from the selected object.
A functional test is included and provides an example.
The timepicker does require JQWidgetBox-Timepickr which loads with ConfigurationOfJQueryWidgetBox from the Metacello repository. 

Cheers
John
