Module development and code questions

I have a content type that i created using cck.
Now this type is a product (ECommerce) and need to customize it's behavior using the product API.
But i don't actually have a module file in which i could put this hook implementations.

I thought CCK could allow this by calling hooks further down like: (my type name is style)
CCK_Style_productapi

does this exist?
what do you say about such idea.

tnx,
hed

I would like to be able to present data about a game that is played in my community. The setup is fairly straightforward. There are an arbitrary number of players and an arbitrary number of rounds for any given instance of the game. In each round, each player presents a piece and the piece is scored by judges. Winner is the player with the highest score. I want to store a variety of information about what each player did in each round.

The Buddylist module is one of the fundamental pieces of building a social networking site with Drupal. It is a good piece of work with a proud history of developers and maintainers, and has been deployed on some very prominent sites. As the current maintainer of the module, I had the opportunity to add many features to it while updating it to be compatible with 4.7. Alas, there is not enough time in the day, and I'm falling behind with the issue queue. In addition, there are many feature requests that make a lot of sense (and even patches to add great features that need testing). Finally, there will soon be a necessary update to be ready for 4.8/5.0. It is clear that if this module is to remain a vital and interesting addition to the Drupal family, more developers need to be involved with maintaining it.

If you value the Buddylist module and depend on it for your sites, and are in a position to help out, the following positions are available:

• A dedicated 4.6 branch maintainer. There are many issues that are specific to 4.6 that merit fixing.
• A dedicated 4.7 maintainer. This person will have the freedom to add features to 4.7. I will work directly with you and assist as best I can.

Has any developed or know of a developed module for tracking UPS shipments? I am in the beginning stages of building a Module but if its been done there is no reason to rack my brain too much.

I am having difficulties with variable_get.

If I set variable_get in a module:
variable_set('module_variable_name',$value);

the variable is set, and I can get it with
variable_get('module_variable_name','0');

But, if I change the value in the variables table, and call variable_get, I get the original value, not the updated value.
I have tried deleting the cache, and sessions but I always get the old value.

Doesn't variable set store the value in the variable table?
and doesn't variable_get retrieve that value?
