Just wanted to let you know guys that , Paypal as you must have heard had blocked donation accounts of Wikileaks and even a new open source decentralized social network known as Diaspora, however a new payment service known as "Stripe"http://stripe.com/ came to the rescue, and also offers much fair Pricing like 2.9% + 30 cents per successful charge. No setup fees, no monthly fees, no card storage fees, no hidden costs: you only get charged when you earn money.
Earnings are transferred to your bank account on a 7 day rolling basis.

Also, came across yet interesting free payment service known as Dwolla
https://www.dwolla.com/default.aspx... , and this company has really interesting model. $0.25 flat fee/transaction. bank-to-bank direct; no middlemen.

Hope these can be integrated into the E-commerce core add-on or as add-on package to the E-commerce block
