Custom Twitter programming, suggestions wanted

Hi all, I just ran across this site, lots of cool info around, I've worked with twitter in the past and have done some scripting, so I was considering writing something new, maybe start another web site if it was popular enough.

In the past I have written a script for a bot which tracks a certain keyword and then RT's the tweet once every 5 minutes, I also recently was playing with the OAuth side of things, and have figured out how to make it come from my application (eg: via "my cool app")

I'm looking at this as a utility for:
Scheduling tweets from a big list (paste in and let it go through one at a time over time)
Maybe sending messages to users who tweet about a target word/follow them
Random tweets inserted for promotional purposes
OAuth authentication

What do you think?
Name?
Functionality?
How about monetization? (Ideally I can make a buck on this too...)
This would probably be a hosted solution, so anything I can get toward hosting is always nice.

More thoughts:
You sign up on the web site, make your profile, yadda yadda...then you create a new campaign. In a campaign you define search phrases, you connect one or more twitter accounts via OAuth, you define one or more custom tweets which could contain your special links, etc, and you're good to go.
On a regular basis this bot will pull the latest updates matching your search terms and send a couple generic retweets to make your feed look a bit more legit.
After that is complete, each account will send one of your custom tweets to one of the most recent results of the target audience.

how about the functionality to send @replies to all relevant posters (ones with your selected keyword) but with a timer functionality so that there is a preset time span between each post the script sends. Would look more natural to Twitter?
