I was actually thinking more along these lines:

1. Activating a plugin:
- get_option('my_main_file'); This option contains the path to the file 
and the version number.
- if true -> check the version
     - if current main.php is newer -> update the option
- else -> add the option

2. When loading a plugin check if class is defined/functions exist, etc. 
If not:
- get_option('my_main_file');
- include main.php at the path from the option and define the class/add 
constant etc.

Can also look at get_option('active_plugins') to figure out when more 
than one plugin will need main.php.
