It seems as this will be the day of the updated End User Computing Flings at VMware Labs today.
ThinApp Factory was updated to version 0.3.1 and now comes with the recently released ThinApp Version 4.7.2. ThinApp Factory is a virtual appliance which can be used on either a ESX server or a VMware Workstation. With TAF you can automate the packaging process for virtual ThinApp applications.
For more information please visit the Fling site over at the VMware Labs or read my articles:
There is also a ThinApp Factory Installation Guide which can be downloaded from the VMware website.
