GPL 3 pack (web surfer/ip phone/messenger)

Hi,

I don't know if I should post in the request new app section and separated in three posts or not, but since I need to explain myself I decided to post it here, If I did wrong, please moderators apologize me and fix it for me...

I need to prepare a precompiled/preconfigured pack of portable apps to a group of students (these students are Spanish farmers from hills in the Andes, extremelly poors and that varely read or write, this will be their first approach to IT's in most cases, and is part of a project to keep them away from drug farming and/or integrating rebel's groups) then I need to use full OSS apps and avoid the use of those apps that request to accept anything (even if the accept thing is just branding), that mean that I don't want to use Firefox nor Chrome, for example.

I want to use something like Skype, but not skype, I don't know if wengophone, ekiga or something like that have the same features (free calls to another wengophone, ekiga or similar). Can somebody give me some light on this?

I need to use a web surfer, but without the "Accept" thing so I already downloaded the Chromium portable available on sourceforge (yes, I searched before posting... lol).

I need Gtalk or pidgin or miranda preconfigured so the student just need to type login and password, without configuring the gtalk stuff.

Chromium will have links to Google Docs and Calendar (heavilly using Chrome extensions) and a specific theme.

I'll also use LibreOffice and the menu from here.

They will be using mostly winXP at rural schools with satelite internet provided by the government, and 2Gb pendrives.

Anything else you whish to suggest?

Thanks in advance.
