Hi – great question!
Essentially, yes, you would require a license for each separate installation (and something like our business or developer licenses may be more suitable for you in that situation).With regards to multiple currency handling, I’m afraid that’s not really something where we can offer guidance – it’s really an issue with the underlying ecommerce engine (WooCommerce itself, in this case) and it would probably be worth touching base with Woo’s own support team to gather their thoughts as to how you might deal with this.
Does that clarify things?
