I just ordered Blackberry and it seems best way to play roguelike on it (good fit for gaming while in work - short, often interrupted periods) is to use SSH/Telnet connection.
I'm aware of servers for DCSS, but I'm also exploring other possibilities. Small FOV in game would be a nice feature, since screen estate is limited. I like hack-alikes in general (POWDER, Infra Arcana etc.), but Nethack is not for me.
Maybe in the end I'll go with self hosted solution, but first I'm looking for hints, since Google didn't yield any meaningful results.
