Cyberzombie, cool idea!

Maybe I was too hasty to dismiss the idea, MSD. So...
Here is my 5-minute treatment of the new and improved Language skill (you may want to change the name)
Language (Int)
While mages concern themselves with musty tomes written in forgotten tongues, the rest of the world is speaking in a myriad of living languages. These languages are thriving, changing, vital windows into the culture, people, and traditions of the world.
All characters begin with one or more automatic languages (typically Common is among these). These are decided either by a character's race or the region they hail from. In addition a character has bonus regional languages that are part of the character's Each language has sister languages, which have a similar alphabet, structure, or ancestry.
SPECIAL: When you spend 3 points in the Language skill you may choose to erase those points from your skill and instead move one of your regional/sister languages to your automatic language list, thereby gaining fluency in that language. At the GM's option, certain other foreign languages may be selected according to your character's experience.
SPECIAL NOTE: This skill replaces the anthropology element of Knowledge (geography)
Sister Languages (as per SRD, suggested that you customize these to your world!!)Elven Group: Elven, Aquan, Sylvan, Undercommon
Fiendish Group: Abyssal, Infernal, Yugoloth
Draconic Group: Auran, Draconic, Ignan
Dwarven Group: Dwarven, Giant, Gnome, Goblin, Orc, Terran
Common Group: Common, Gnoll, Halfling
SKILL CHECK
Language DC Task
Automatic.............Speak native (automatic) languages, identify common cultural elements connected to native languages (music, writing, dress, weapons, architecture, etc)
10.........................Understanding a dialect in your native language
12........................Understanding the gist of a sister language
15........................Understanding the gist of a regional language, Identifying subculture elements connected to native language (e.g. dialect)
20........................Identifying sister culture elements connected to native language (e.g. sister language), Identifying regional cultural elements connections to secondary language
25........................Identifying a subculture element of a sister or regional culture
+5.......................Language is based on non-human vocal chords, or other nearly impossible to recreate sounds
SPECIAL: The Language skill can be used in place of the Sense Motive skill when determining if someone is from your native culture or not, or whether they're a native speaker or not. In this case it is opposed by a Bluff or possibly Disguise check.
NEW FEAT: Trade Tongue [general]
When confronted with foreign languages you are able to effectively communicate using pidgin and gestures.
Benefit: You can make a Language check to understand the gist of what is being said, even when confronted by a completely foreign language (one that is not on your secondary languages list). The DC is 15 for a language you’ve been exposed to, 20 for foreign languages, and 25 for exotic tongues. You ignore the +5 penalty for non-standard languages. This feat only applies to spoken language.
