MDT from Single Site for Multi Domain OS Deployment

Hi all,

We are looking for a solution which will make it possible to use MDT from a single site to deploy Windows 7 or Windows 8 and join different domains of different customers without trust relationships between domains.

We are a service provider which supports different customers with separate domains. At this moment those different customers have their own WDS server on site and administration is time consuming because a lot of hardware changes occur.
We are now searching for a solution which is easier to manage and one of the solutions we are thinking about is to install a WDS server in our office and use MDT for some custom task sequences but just build one image with all the different driver packs we have.

Does anyone know how to deal with this from our point of view. All tooling I can find is based on Enterprise clients with one Domain Forest and maybe some different sites but all in one domain, which makes deployment a bit easier then in our situation I guess as we are looking for a solution that supports Multi-domain deployment.
Hope someone might experienced this before and can help us in the right direction. If someone has experience with additional tooling which might help us I am more then interested to know how the tooling helped in solving this.

Preferrably we had a tool which was Multi-tenant and multiple domains could be managed from a single console, but I think that tool just doesn't exist.

Hope someone is able to help us in the right direction. Please let me know if you have any tips or did experience the same while making a Deployment plan for the service provider you are working for.

Many thanks in advance!
