Robert,
I ran into this with Count My Clicks and I solved it by using custom hooks. 
There's no need to alter the way the core handles plugins. Is this what you 
meant by "fancy hooking around init":

count-my-clicks.php:
// Do all my plugin init stuff first, then:
global $cmc_loaded;
$cmc_loaded=true; // Leave a note for dependent plugins not yet loaded.
do_action('cmc_loaded'); // Signal dependent plugins already loaded to sart.

cmc-dependent-plugin.php:
function init_cmc_dependent_plugin() { // Wrap the guts in a function.
// Put all the cmc-dependent stuff here
}
if ( isset($cmc_loaded) ) init_cmc_dependent_plugin(); // Call the function; 
or
else add_action('cmc_loaded','init_cmc_dependent_plugin'); // let it be 
called later.

But what if your plugin depends on a plugin that wasn't written this way? We 
could have an official Plugin Template with these init lines added, or you 
could distribute your plugin with the needed plugin included and modified 
for your needs.

Cheers,
Andy
