I'm interested in your ideas, particulary "Wind Me Up" and "Heatwave"-- quite the fan of Prohibition-era stories, particularly those with an underworld focus. Not sure which kind of characters you'd like to take as a vantage to this, but I'd like to toss out a couple of ideas.
Steampunk, on the other hand, I've more or less a vague notion... your description almost comes of as low-tech cyberpunk, but I rather thought of it as sci-fi as envisioned by Victorian minds or Romantic-era writers. Certainly, we could discuss this and find some common ground, as I could see the 'setup' you've described taking a different turn, if that's the case.
Anyway... time has told me that replying with too much detail and discussion might dissuade other interested writers, and I've no intention of doing that-- especially since I've been a bit unreliable of late. So, please take a look at my post history-- might take a whilie to find some storylines-- and if you think our writing styles mesh, please let me know and we can discuss via PM any further possibilities.
