Ask HN: Multilingual E-commerce Shopping Cart Recommendation

I have some clients who need to have a multilingual site, multiple currencies and gateways.

Business catalyst and shopify do not seem to provide i18n.

I have been looking into ubercart with drupal, magento, spree and OFBiz.

It seems that ubercart does not support multiple currencies. And Magento community version has a limited functionality.

Should I build multiple "one language, one currency" sites instead? Any other suggestions? Thanks!
