Not all RPGs work like D&amp;D. The best you can do is to choose a game which does not rely on wargame-like details such as line-of-sight or movement-per-round. First couple examples off the top of my head:

Storming the Wizard's Tower (by Vincent Baker, still in development, unfinished, play at your own risk), which is basically "D&amp;D done a different way", abstracts advantageous positioning and battlefield stunts into a supplementary die roll, leaving players the freedom to describe the battlefield in detail.

Anima Prime (by Christian Griffen, available free as a playtest release, but still very solid) is all about flashy moves and interacting with the environment in cinematic battles, but abstracts maneuvering into changing dice pools. Describing your actions with great flare is the heart of the game.

Beast Hunters (by Christian and Lisa Griffen, available for sale or as a free SRD) is the immediate precursor to Anima Prime and it clearly shows that such a line of thought also works for more gritty, down-to-earth battles, and not just for uber-cinematic superhero showdowns.

And all of the above are fantasy games with heroic PCs, monsters and lots of fights. Should you be out for a real change in pace and tone, instead, the possibilities are (literally) thousands.

Without a map or miniatures, how to best determine line-of-sight, etc?
My wired interface (eth0) is connected to a corporate VPN (which disallows all sorts of things via a proxy) while at the same time the wireless interface is connected to a guest wireless network on eth1 which has no restrictions. 

How can I configure things (Ubuntu) in such a way that my wireless handles all browser connections while my wired handles the rest (nfs, etc.).
