Hi Ari, we are looking to run courses outside the US as I mentioned, and we may offer some discounts to particular audiences or in specific cases, but I don't have anything concrete I can tell you right now.
What I will say to your specifc example though is running the training in the UK might not actually save you travel expenses, hotels in the UK are probably as expensive as those in Redmond and you will want to stay close to the training location... the last thing anyone wants after a 14 hour day talking about Exchange is a one hour drive home... becasue we will start again at 8am the following day and I'm not a fan of latecomers...
As soon as we open up registration for other locations I'll be sure to let everyone know.
