Greetings, We just received an inquiry from a customer who needs a small module for his PE installations at short notice. Unfortunately our PE licenses haven’t arrived yet, hence we need to work with CE. Would anyone know if the code we develop for CE would be compatible with PE? This module relates to the Articles/Products table, and we need to create a couple of new tables. On the front end, it effects the product details page and the shopping cart (checkout page). The product-configuration page on the Admin side is also effected. Thank you for your feedback. Ashant ---

Hi Ashant, > Would anyone know if the code we develop for CE would be compatible with PE? the code for PE and CE is nearly the same except WYSIWYG (because of the license) and SOAP i believe. So your code shall work properly. BTW: Do you see a possibility to make the module available to public under GPL? Maybe you want to go for dual licensing as well in this case? Cheers ---

Cheers[/QUOTE] Hi Marco - never thought about this so far, but would like to understand the legalities of this. Any pointers on info related to dual licensing models would help. Thanks Ashant ---

Hi Ashant, maybe this link is helpful: > **[Multi-licensing](https://en.wikipedia.org/wiki/Dual_licensing)** > > Multi-licensing is the practice of distributing software under two or more different sets of terms and conditions. This may mean multiple different software licenses or sets of licenses. Prefixes may be used to indicate the number of licenses used, e.g. dual-licensed for software licensed under two different licenses. When software is multi-licensed, recipients can typically choose the terms under which they want to use or distribute the software, but note, that the simple presence of multiple li... Cheers ---
