Module development and code questions

I have been using flexinode to create nodes of different types (like product attrubutes, product image etc). Now I am looking for a module which will allow me to create a node (say product) which itself can consist of a number of such flexinodes (like one product attribute node and one product image node inside the product node). Has someone written such a module which i can use or is there anyway i can use a combination of the existing modules to get this functionality.

Using 4.6...

I have a node type which is basically a hacked version of page. It's pretty simple stuff. What I was is an opportunity to change the content of the node (that is, the displayed text). 9 times out of 10 the node content will be displayed as normal, but just occasionally, when the right conditions are met, I want to replace the displayed node content with some hard coded text. I don't want to permanently change the text in the node - next time it gets displayed if should show the node's text as normal (unless my conditions are met again).

Looking through the API I found hook_view(), which appears to do what I want. I hacked together an implementation of this function that just changes the $node->body value, and that looks like the answer:

function mod_view(&$node, $teaser = FALSE, $page = FALSE) {
  if( condition ) {
    $node->body = "Changed content";
  }
  $node = node_prepare($node, $teaser);
}

However, I'm very new to this, and I'm not sure of the knock on effects of this. Have I found a decent solution, or is there a better way to doing this?

Ha All,

Is there a module to set a password for some directory using .htaccess files? i mean a module which by using a button set a password for a directory inside home of a user? For Example i have picktures on gallery and wish not share all the Images. Then i put a .htaccess file in image directory and get picktures hidden?

I know that Drupal doesn't have any classifieds modules, but it seems like classifieds modules generally have ads in categories. Instead of categories, I want my ads to be tag-based like craigslist is. Anyone have any ideas on where to start?

Everything works great, but I'd like to have everything set up so that when a user uses the ImageManager, they have their own directory.

Has one done this or knows how feasible this is?

I very much like what frjo has done with the vote up/down module.

It utilizes the voting api, actions, voting actions, and links modules, along with some cool AJAX. Well done frjo.

Vote up/down mimics the reddit.com style of voting, rather than digg.com. I, and I'm sure many others, would like to see a Digg Voting module created as well. I'd like to do this myself, and actually have started experimenting based of the vote up/down module, but I am not very good at php yet, let alone AJAX.
