[Mediawiki-l] iframe and gpl license

[scandisk at gmx.de]

Good afternoon,
I have a question related to integrating a mediawiki into a proprietary software via an iframe.

I am planning on doing two things:
1. Write an open-source extension for mediawiki, that allows automatic sign on/account creations triggered by certain GET parameters. This could generally be used from any site by anyone.

2. Create a page inside of a proprietary portal, that includes an iframe to a separate mediawiki. The link to the mediawiki contains some GET parameters, that the mediawiki extension uses to identify/sign on the user or create a new account, if that user does not already exist.

The mediawiki runs on a separate server at a different location and is otherwise entirely unrelated to the proprietary software.

I have the following questions:
1. Does the GPL allow to integrate a mediawiki inside of a proprietary software via an iframe, without requiring the proprietary software to be published open source as well?

2. Does the provision of GET parameters in the src of the iframe (in order to realize an automatic account creation in the mediawiki) make a difference?

Has anyone ever been in a comparable situation?
