I worked on an inline date picker yesterday. It makes use of a slightly modified z_calendar.ipl file and jQuery. Figured I would share it.
Requires jquery-1.3.2. (You'll see the script reference, you'll need to download and place into that location, or change to your own location).
Tested in IE 7, 8, 9 and FireFox 7 with TeamSite 7.2.1.
