I just implemented possibility to add multiple shoping options.Yesterday I build small markup module which venders the shopping steps (1. cart, 2. information, 3. confirmation, 4. payment, 5. order complete).
Also some minor tweaks here and there. I will also add option to choose currency (I am not planning to support multiple currencies, but possibility to choose what currency the shop uses will be there). Hopefully I get today all wrapped up and can commit it.
