No More DTO
When people talk about "transfer" and that they need some object (assuming DTO) to do a "data transfer" I would review the need for this transfer.
DTO is very similar to Memento design pattern so DTO could be called a variation of it. Memento could be useful for saving state of some object. We create Memento if we need some kind of client-side caching where we store a local state of server-side object. See a discusion regarding DTO and caching in comments below.
But when somebody talks about the need to "transfer" some data I would suggest to get the data directly from the source! Distinquish "transfer data" and "store state". No need for a transfer - just let an object that needs the data talk to object which is responsible for holding the data. Find object who demands the data. Find object which holds the data. While in your demanding object, get the data from the direct source. This is so easy.
