ExpressRoute in Azure - L2 connection

Hello, there is a new feature in Microsoft Azure called EpressRoute.   Currently, ExpressRoute is available only  in the US through the partners in US, so i can´t try in in EU. Our cusomer would like to use connection to MS Azure based on L2 layer ISO/OSI reference model, that means connection without "routing". They use VLANs in local network, which they would like to "extend" to Azure environment - for example they use some device - card readers where is not possible to set up default gateway so network packet can't be routed as L3 connection (and they do not want to use Proxy ARP). So as I understood in ExpressRoute is possible to connect to Azure with dedicatet and guaranteed private connection line (not over public internet). 
But my qutestion is: 
Do anybody have a experience with Expressroute, is it possible to connect Azure networks and services trought L2 connection (one site in customerś location and second in Azure) ?

Thanks in advance,
Michal
