I have released a new version of Gladiators and ariannexp that keep in sync with changes on Marauroa. There aren't any gameplay improvements, but I am setting the base for a improved game that should happen soon. BTW now ariannexp is totally compilable and runable in Linux using autoconf. You need GCC 3.x in order to compile it.
If you feel nice enough I would be looking for help to write a simple SDL client, I would create all the GFX for you. Just step on the IRC channel or arianne-devel mailing and I will give you more info.
