I'm looking for a means of constructing a Timed Evaluation Copy of an
application I'm building, so that the application can't be used after 
a pre-set period of time (days) has elapsed.

In ST/V (VSE) and Enfin (Object Studio), the code to accomplish this will
become part of the deliverable, which can't be de-compiled (easily, at
least...), so the routine can't be defeated easily.  However, VW's
in-built de-compiler requires me to look for an alternative way of 
accomplishing this.

Any pointers (or even recommendations of a 3rd-party package) that will 
allow me to implement this Timed Evaluation Copy in VW 2.5 (NT & Unix) will 
be appreciated.  I'd prefer not to embed anything in the registry, etc.

Thanx!

P.S.  Does IBM Smalltalk have this in-built de-compiler as well?
