I've seen your application and this kind of integration is useful for certain purposes.
Since last year I'm struggling for finding a standard way in validating/masking the input in Tersus, see my earlier remarks in this thread. There are many types of fields like zip-code, iban, telephone, vatnumber, clearing-code, etc. I'm using in my Tersus applications.
And because there are already 2 feature requests (#214 and #215) AND you Tersus guys are looking to jQuery, this may be a standard solution (however as David said, many details had to worked out).
For best results, use the Firefox browser..
