I'm largely guessing here, after spending a few minutes looking at the 
code for Vend::Payment::BusinessOnlinePayment, Business::OnlinePayment 
itself, and a couple of Business::OnlinePayment processor modules.

My first assumption would be that MERCHANTKEY and CLIENT_ID are 
analogous to a password and user name, and should be passed as the 'id' 
and 'secret' parameters to the onlinepayment module, i.e. something like:

	Route onlinepayment processor IPCharge
	Route onlinepayment id my_client_id_value
	Route onlinepayment secret my_merchantkey_value

These get passed to your module's 'content' method as the 'login' and 
'password' hash entries, and you can then remap them to the the elements 
required by IPCharge in various places, such as the map_fields, 
remap_fields, or the submit method in your module.

Assuming that IPCharge actually requires more complex credentials than a 
user name/id and password/key, then just pass the additional values:

	Route onlinepayment client_id foo

It looks like these get passed to Business::OnlinePayment's new method 
and wind up as attributes and methods on the Business::OnlinePayment 
object, i.e. you can then use:


in methods like map_fields, remap_fields, or submit.

You may want to ask questions about which method is the best place in 
your module to do the mapping on the Business::OnlinePayment e-mail 
list: bop-devel at 420.am.
