Mmmnn, Chilli!! Great idea to have a seed swap.
Better get in quick - this season is fast drawing to a close - if you germinate the seeds now, you may have a chance of getting a harvest before the colder weather sets in. Otherwise, the next season is only a short 6 months away!
I have 50-60 varieties growing, but becuase they're all growing in the same area, the next generation of seeds will likely all be hybrids - this has certainly been the case in the past. It's cool to grow a new variety, but it's also annoying to get a completely different chilli plant from the one the seeds were harvest from. As such, I don't think my seeds will be much value.
I've great success with the giant jalapeno chilli pods you can get from Woolies or Coles - these germinate very quickly and grow massive pods.
