If Turbo versions of Delphi are not available, it is a great idea to have<br>
them as PR to get students getting free versions to learn on. Without<br>
Embarcadero losing money on commercial sales.<br>
<br>
Interested to hear others ideas how such editions could work.<br>
<br>
My ideas:<br>
<br>
-Preventing installation of components as in the past is simple - but some<br>
large scale commercial programs could still be made, so I think it needs<br>
more.<br>
<br>
-Either disabling printing if included (Rave reports) or all printing<br>
carries a water mark "Student Edition - not for commercial use".<br>
<br>
-All program windows contains some signature eg "Student edition" in the<br>
title bar<br>
<br>
-some smart restrictions on what can be produced.......eg cheap or free DB<br>
licences limit to often only 5 connections. Maybe limit units to 4000<br>
lines of code, or forms to 30 components total, and listviews and grids to<br>
200 lines,<br>
<br>
-Programs might only run for 1 hour maximum and exit with a reminder screen,<br>
or will not run at all after say 1-2 years.<br>
<br>
-Alternatively charge strictly on a usage basis - eg start with $20 free<br>
credit. Every compile takes 10cents of credit, every debugger run takes 20<br>
cents off, editing takes off 1 cent per hour. When credit is used up IDE<br>
stops working, and you have to uninstall and reinstall. (Transaction based<br>
charging like this is a favourite of mine, incorporated into some of my<br>
programs).<br>
<br>
-Expiry date on IDE, have to uninstall and reinstall to get more.<br>
<br>
-Student edition could cost say $25 or be free, depending on how restricted.<br>
<br>
A combination of more than one of these would mean commercial developers<br>
would still get the real versions, and be not too mean on students.<br>
<br>
Choose what is good to limit, and let them otherwise have a fully functional<br>
version - in reality they won't be writing very large programs, so that is<br>
what to limit.<br>
<br>
Personally I would favour the combination of<br>
-Watermarks on printing<br>
-limits on grid size and number of components on a form<br>
-programs run for 1 hour maximum.<br>
<br>
