I would say it's not impossible. Modifying the pod executable to change to hard-coded IP addresses of servers should be possible.
The harder part is to set up a server with the server software running. We could reverse engineer this server too (though with new patent laws ... I m not sure we are authorized to do this anymore

) but it would be quite hard I think. I'd better spend time on creating a network layer on top of Sik's TE ....
To answer to the first question of the topic, (I m not sure I m on the right thread , though ..) I must say that there is another game for me beating pod in terms of long time play : Civilization.
I play civilization (the 1st version ... not the #2 nor the #3 nor any other shit that came after this wonderful revolutionary game) and I play it since it appeared (1991) ....
I still enjoy it a lot and every game I play is a wonderful one ... I don't think I could feel bored , there are so many combinations ....
I still enjoy pod because there are people playing it (my friends actually ...

) , because there are always new things coming and I really like the background. But even with this, I think I would have been bored if there weren't the GSs (game service and ... grouikstocks! ).
