Samsung Plasma vs Android in-app billing
What is the difference between the Androidn In-App Billing and Samsung In-App Billing Plasma library.

http://innovator.samsungmobile.com/cms/cnts/knowledge.detail.view.do?cntsId=9984&platformId=1 

What I understood until now, that the later uses Operator billing instead of Credit Card billing, is there anything else?

Can I submit an application that uses the normal Android In-App Billing to the Samsung apps store, or I have to implement the in app billing using their library?

I'll appreciate any additional notes regarding this library..
