At this early stage my feeling is that the project would approach edge development from two positions - trying to translate what I know about the market and my manual edges into a bot, and secondly harvesting data from the market which can then be analysed to uncover further edges.
My approach will be to put those guys onto a path of learning about the markets initially, spending some time staring at the ladders, and over time begin to introduce my conception of how the market moves.
Be great to hear from anyone else who has done something similar and any experiences they'd like to share - trading is usually a solitary pursuit so will be strange sharing it with others

A practical question I had - is it best to create the bots and then deploy them separately, from our own betfair accounts, or to pool our resources into one and then split the winnings? Both of these have obvious pros and cons, commission being a big factor, so any opinions on this would likewise be interesting to hear.
