rogue source wanted

[rbt]

We are a group of computer scientists looking for a complete Rogue
(or Rogue-like games) source in order to implement some additions.
What we would like to do is:
1)implement some interactive features as in Phantasia (possibility
of fighting ,talking and exchanging items with other players)
2)raise the complexity of the game (more levels,shops/merchants,...)
Of course we will not be going to sell the game,and will be wishing
to post it in the net or to the sender of the original source.
