Hi. My name's Michael. I've been lurking for a bit, but I finally decided to post.
While discussing diceless mechanics and forum-based roleplaying at another site I had an idea for a (semi)GM-less forum game. I'm not sure how 'do-able' it is, and since I'm not a programmer of any sort, I'm fairly certain I'll never know. This was a sudden 'hey, this sounds cool' kind of thing, so I thought I'd post it here.
The concept is built around random generators of the sort you can find at Seventh Sanctum. Of course, this all also suggests a group of dedicated players. Basically, a genre is decided on (space opera, horror, contemporary fantasy, whatever). The group of players come to an agreement on the generalities of the game world, and basic target benchmarks for DCs. Then, as a group, they create a collection of unnamed NPCs (and Beasties, if appropriate) in which ever game system they'll be using; I'd suggest something simple, and probably diceless. These NPCs are entered as a 'list' for an Encounter Random Generator. Or, an alternative would be to create randomizers for all character stats.
Then, each player creates situations they'd like to see happen In Game. They come up with one short, descriptive sentence per each number of players involved in the game (for example, if there are five players Tom writes five sentences). These are entered as a 'list' for a Situation Random Generator.
Gameplay is semi-freeform, players create the narrative as they go. Whenever a character becomes involved in conflict with an NPC they use the Encounter Random Generator to create the opposition's traits. Conflict proceeds normally. Either the player or another player may narrate the outcome. I'm thinking a random generator for each individual Trait would be better suited for this.
At any time in the game, any player may roll on the Situation Random Generator and bring the result into play. The player has the right to play the situation with his own character, or toss it into another character's path.
I realize that play should be policed in some way. Maybe a player takes on the role of Judge for a certain amount of time. Judge duties should rotate on some type of schedule.
What I'd like for the Random Generators would be something along the line of Invisible Castle. Something that documents the rolls and provides a tag to be placed into the post, similar to a dice roll.
These are just some basic ideas of course. I realize it needs a lot of fleshing out, but I like it for what it is nonetheless.
