I have moved script.c from server/ to common/ and embedded the python in both 
server & client.

A snapshot of my tree is attached (after applying the patch remember to run:
automake && autoheader && autoconf && ./configure --with-python).

Now I'll add:

  * support for server commands;
    e.g.:
      game.xsize = 40 # from the client this will send a "/set xsize 40"
      game.start()

  * mirror more things from c;
    e.g.:
      for player in game.players:
          print player.name
      for unit in game.player_ptr.units:
          if unit.moves_left:
              unit.move(NORTH)

  * more callbacks.

In the medium term a client without gui can be useful for running client AIs, 
but the code can already run separate python threads in the server (or in the 
standard clients).

I'll probably try to add support for tcl (because it's simple to embed) and 
happily accept patches for perl, java, guile (because they are populars ;-)).
Probably it will be possible to freely mix modules in different languages.

Comments?

ciao
