I think you mix up something. Resources/Private/PHP is the location for 
3rd party libraries (e.g. Resources/Private/PHP/PHPUnit or 
Resources/Private/PHP/phpMyAdmin)

In the case of eID-classes it depends on the purpose I guess. For 
instance: when your eID implementation acts like some kind of API to 
your extension you might put it in Classes/Api, Classes/Gateway, 
Classes/Interface or similar.

After all, an eID class could be just a regular class that might be used 
in several places.
To avoid that the class is instantiated in non-eID-usecases I usually so 
something like:

class Tx_MyExtension_Api_Customer {
	public function getCustomerById($customerId) {
		...
	}
}

if (isset(t3lib_div::_GET('eID'))) {
	$customerApi = t3lib_div::makeInstance('Tx_MyExtension_Api_Customer');
	$customer = 
$customerApi->getCustomerById((integer)t3lib_div::_GET('customerId'));
	echo t3lib_div::array2xml_cs($customer);
}

This is just dummy code, but you get the point - you can reuse this 
class from other places like typoscript or from other extensions.

So, I think it is probably not the best idea to add the convention that 
eID-classes should reside in a special directory cause it just depends 
on the use case.. But I'm open to be convinced otherwise ;)
