21 * @file gnunet-gns-fcfsd.c
22 * @brief HTTP daemon that offers first-come-first-serve GNS domain registration
23 * @author Christian Grothoff
26 * - the code currently contains a 'race' between checking that the
27 * domain name is available and allocating it to the new public key
28 * (should this race be solved by namestore or by fcfsd?)
29 * - nicer error reporting to browser
30 * - figure out where this binary should go (is gns the right directory!?)
