Maybe I am too pessimistic here, but I don't foresee too many users of netmap as long as it remains just a mechanism that potentially can greatly speed up things if you manage to write your own applications that do those things via netmap. Full TCP/IP stack with sockets API on top of it and lots of available applications on top of that is one thing, an interface to a network card is a totally different thing on a scale of usability (especially the by the end-users). -- Andriy Gapon
