Thin Client Strategy

Hi All,

I am preparing a general solution for clients to move to thin client.

Typically i feel there will be following kind of application that will be used

1) Microsoft office
2) Bussiness application
3) IT application

I am looking for pointers on how to do the assessment of their current set of application / infrastructure. IT would be great if someone can even share a document where by he might have done some assessment

Also what are the varios thin client solutions available.
