Module development and code questions

I'm building a new module. I wanted to reuse some code that I picked up within my module. THe code is built with two class instances. But, if I try and use a "require_once()" statement to include them, when I execute a member function in the class, I get:

   Fatal error: Call to a member function on a non-object in 
   /drupal/modules/cloak/antispam/anti-spam.class.php on line 74

If I copy the classes into my .module file, and then instantiate and call them, I get an error, very similar, like:

   Fatal error: Call to a member function on a non-object in 
   /drupal/modules/cloak/cloak.module on line 521

In both cases, the "offending" code is:

   $crypt->HTML_Crypt($this->antispamemail, 1);

The HTML_Crypt class is included and works. If I call all of this outside of drupal from a separate PHP code file, it all works fine.

Are there any issues I'm running into with calling Class functions, etc. from within Drupal? If so, is there some way around this so I can utilize these classes?

TIA.

I've been fooling around with header inspection, DNSBL lookups, attempted exploits, user agent tracking (bad bots), and access/ban lists.

If this experimentation were to ever make it into a drupal module, what features would be the most helpful/desired? In addition to what I've listed, what other features can you think of?

Thanks for the feedback.

I was wondering if anyone has developed a tool / script capable of "importing / updating" users from either a CSV or database? I need to migrate about 350 users to a new Drupal based site and a tool like this would be great for users & myself!

I'm working on a cloaking module which hides email addresses (as per my conversation and layout in Privacy/security of a website).

I've run into a small road block, since I'm not the greatest coder. I've got the basic structure in place, and associated functions burned in. However, I'm having a hard time modifying the eregi_replace() call (as ripped from the HTML filters) to call a function to act on the filtered/replaced text. Here's what I'm looking at:

$text = eregi_replace("([ \n\r\t])([A-Za-z0-9._]+@[A-Za-z0-9._]+\.[A-Za-z]{2,4})([.,]?)([ \n\r\t])", '\2', $text)&#59;

What I need to do is have the "\2" matched text passed through a function. So I tried something like:

$text = eregi_replace("([ \n\r\t])([A-Za-z0-9._]+@[A-Za-z0-9._]+\.[A-Za-z]{2,4})([.,]?)([ \n\r\t])", cloak_address('\2'), $text)&#59;

One of the custom node modules I am developing for my site requires the ability to customize the "teaser". Rather than take the first "x" bytes as specified in the parameters for the node module - this module needs to provide the user with the ability to write their own teaser. Is there a hook or other method that would allow a module to set the content of the teaser and override the default behavior?

I'm working on an email cloaking module, as per the conversation thread at:

Towards the end where I commented with some specifications.
