Goals:
- text-based protocols, telnetish, TCP/IPish
- comminucate over sockets (requests to services), both in client-
(connect) and server-mode (bind,listen,accept)
- there should be no difference whether we talk to sockets, pipes
of an external process or a file
- how events are colleted (select,poll,kqueue,/dev/poll,epoll,etc.)
should be abstracted
- should be usable in single- and multithreaded environment
- we should scale, but not in the webserver-style (which would be
optimization done too early in the wrong direction!)
- protocols should be designable like a Russian Nested Doll for being
fast in business layer to device new protocols suiting the problem
- reach the 100MBit/s sustained transfer rate (yes I know, there are
Gigabits/s NICs out there, but their speed is almost impossible to
reach)
