 Anyway I find that when using tuples heavily it is actually better to define classes/structs for your data, as using t.get<idxHostname>() all the time is no better than t.hostname, and also not clearer.

This has been my experience too - that the get<N>() notation tends to obscure, and effectively introduce another unnecessary level of indirection. As I understand it, what tuples offer is that they're a building block for type sequences, which enable them to be handled generically, ie become the foundation for Boost.Fusion.

Do note, Boost.Fusion can turn structs/classes into tuples (Boost.Fusion.Vectors) so you can use them purely interchangably. Boost.Fusion is also very easy to use, especially if you know Boost.MPL (it is basically a runtime mixed version of Boost.MPL, very powerful, quite easy).
