30 day trial support in ProtectedProductSessionManager

Hi,
    is anyone using the ProtectedProductSessionManager to deliver 30 day
trial serial numbers? I've looked through the code and the associated
serial number class and I can't quite see how the expiry mechanism on
the serial number works. In particular, how the application is made to
stop working once the serial number has expired. The comments indicate
that the expiry is an absolute month number - I can't tell if this is
correct because I can't find the expiry mechanism. Maybe I'm missing
something obvious?

Is my understanding correct that the classes are decrypted everytime the
application starts?

Finally, I'm presuming that this will work with a ToGo deployment?

I'm asking questions in advance of stumbling in to try it in order to
protect myself from the rotten fruit of my misunderstanding :)

The expirty mechanism is not available in the ProtectedProductSessionManager
despite some encouragingly named methods,

That's correct. The existing expiry mechanism used by the Dolphin IDE relies
on some communication with the VM and the ability of the VM to "do"
something to the image that encodes the expiry info in it. We haven't yet
worked out how to create the same effect with a deployed EXE, sorry.
