Module development and code questions

I am building a setup where there will be multiple servers and I would like them to share the same auth. I will have server 1 hosting sub1.site.com and server 2 hosting sub2.site.com. I am going to write a module that allows it so if you are logged into one, then you are also logged into the other when you go there.

Any helpful ideas would be appreciated.

Is there any module with which I can do that:

Any member of the group citationAuthors can create an entry into the citations-pool. Each day the citation-of-the-day is shown in a certain area of the website. This could be used for fortunes, tip of the day and so on.

I didn't find a module to realize this yet.

I want to solve this problem:

Admin creates a content type extended_profile based of several standard-fields (birthday, picture, text-area,...). Every member of the group e.g. "superuser" has his/her extended profile (not more, not less) and can only edit his/her ext_profile.

Normal registred users oder anonymous ones only have the standard profiles.

I found a module and a patch which could be helpful:

Dear Drupal Developers,

I want to develop a specific module, which takes some data from the group of “Data Submitters”, then puts it into a database, and finally shows these data in various formats to the rest of the world.

The question is simple: what is the best way to internationalize these data?

I guess, there will be the other group of “Translators” who are responsible for the translation.

I need to show some special characters in the glossary, for instance ñ, or the phonetic alphabet.

how can i do this, any help arrownd the drupal biosphera.

There is module called "download" in contributions/modules/download directory. It's probably old abandoned module - no change since 1.10.2004 and module owner did not respond. I improved the module features and I would like to create project assigned to this cvs directory. I had problem (http://drupal.org/node/13018) in the past when creating project assigned to CVS which already exists. Could anybody help me and manually assing it in database? I ask in advance not to create dead project.
