Webshop for the SIMtrace hardware

Hi all, I have toyed with spreecommerce[1] on and off and would like to have some friendly users to see if the whole checkout process is working. The shop can be found here[2] but I would like to share some technical details with you. My patched spreecommerce can be found on gitorious[3], for some of the changes I should have created an extension but right now I think I prefer git pull --rebase to see what changed. If you enter your EUVAT number you should not be charged VAT (unless you are in Germany). We are using a CA Cert signed certificate, your browser will tell you that it is dangerous, I think we prefer putting the money into future HW products than getting a signature from a 'trust worthy' org. Shipping cost calculation is a bit of a mess, does anyone know if DHL offers an API for it? The installation has four zones (Germany, EUVAT region, USA, World Wide)? Terms/Conditions and Privacy Policy are very basic and need to be refined, with best effort I tried to make short and clear. Technical feedback, specially on caching, rails (security), etc. is very welcome. holger [1] spreecommerce.com [2] https://shop.sysmocom.de [3] https://gitorious.org/sysmocom-spreecommerce
