Hi Andy,
maybe you missed my previous eMail on this list ... :-)

Please, can you clarify how you *validate* the 'MAS receipt file' from a 
LiveCode application ?

Thanks in advance,

It has a hardware signature so you can make sure your app is valid on that system and has not been copied to another system.  If everything checks out you can then treat the launch as a full registered copy and skip your trial screens.

Each copy gets its own reciept for each computer which will validate,  so while you cant copy an app from one computer to another,  there is no real limit to how many computers a user can install on if they want.
