Your best option is to ask the product supplier.
My guess would be that the translation engine should be easy to use, by calling it directly from the WebHandler Translation method. NetTalk passes all plain-text through this method so you can plug in whichever translation engine you like.
The Scheduling template sounds very much like a screen component, in which case it would need to generate HTML rather than clarion screen controls. So my guess is that, unless Bo has added support directly, this will not work. If you want to see some built-in calendar options, see the webinar on that.
