Anyone using Multi domain on Spree 1.1.. Need it badly...
I'm using Spree as Ecommerce solution and now need to have several customer facing multiple stores with single administration...

Environment:
Spree version - 1.1
rails 3.2
Ruby 1.9.2

I tried using the existing gem http://spreecommerce.com/extensions/128-spree-multi-doman

I suppose, it don't support rails 3.2 and spree 1.1, What changes above extension needs in order to use it in Spree 1.1 ans rails 3.2 ?
