Module development and code questions

I would like to implement a Drupal site based on flexinode module.
I would like to ask to someone else with the same experience how they implemented search on such a scenario.
What I understand is that flexinode lets you search on a specific flexinode type (/flexinode/search/xx), but not across all the types (like standard Drupal search).
I would need some suggestions by you. My need would be to have the possibility to search by taxonomy and by string.
The modules like taxonomy_browser do not work correctly with flexinode.

I've been trying to use the i18n module from CVS with a 4.4.2 system. I had some problems, then patched it with a patch provided by chx. Unfortunately, everything seems fixed except for the "Language" block, which gives multiple language prefixes in the url, eg. "http://yoursite.com/fr/fr/destination/url". I've looked into the code and posted what I found here.

A few thoughts on extending the existent events module. The target is a consistent, modular, and flexible scheduling add-on to drupal. Probably best implemented as a set of modules. The rough specs below are adventurous and probably over the top. I'll try and knock together some demo code, by refactoring the existing event + some additional code as a proof of concept.

I've created this Drupal module to consolidate and add missing feeds into a single place. This module includes the following protocols: RSS 1.0 (rdf), RSS 2.0, Atom 0.3. It does not try to replace the existing RSS 0.92 feed that exists in Drupal core. This module is based on the atom module.

There is a new flexinode field type which allows users to choose a color from a color table. The code for the color table was modified from HTMLArea.module. It is in the modules/flexinode/contrib directory in CVS.

Hello to everyone!

How can I change this function in book.module to have the book navigation block always expanded?
