I know of a program that communicates as an individual launcher for their own game, it's a mod for Arma 2 called City life, if you want I can get you a copy and you can extract it and look through the files and see how it works. It acts just as you said before, a 3rd party app that communicates with the server that can change keybinds, setting and other such things.

What would be the difference between said Class genres? Just their abilities? I would go with what would make us more different, be it RPG or Post. Apoc. Though I think a long-term vote would be at-hand for that sort of a decision.

--(Plug-In Addition Suggestion)--

For the skill system, let us add points with a custom value such add /learn Armor 1-25 so we dont have to spam chat for a minute trying to learn skills.

Seems like we'd need your powerful server you're getting to run a mod like this w/o lag :)

Anyways -- class ideas:
Your typical classes: Priest (Shoot bullets @ teamates and heal them)
Recon - Similar to hunter, but with SMG/Pistols/Shotty ability to blend in with environment? Low HP specialize in supressors (No reduced dmg+range)
Balance - mediocre @ every classes passive stats: Assigned before picking a specific class
Tank - Low Damage, High HP / Shields
Soldier - Profficient w/ M4 and has low hp, but high shield levels.

Sub-Classes:
Scavenger - similar to current looter, more loot from crates, dorito animal loot
Crafter - Good at crafting weapons - Chance to make extra gunpowder, planks , w/e when crafting
Collector - Get extra supplies when collecting nodes
Farmer - TBD since we don't know yet how it works. I figure faster planting times and less water needed etc.

Just my input for experience in MMORPG's
