I'm working alone on an idea.
Plus I work full time as a software developer and have a small baby at home.
I'm trying to find partners who hopefully have more time or at least interest and willingness.
I don't see this being a full time activity at the moment -- I wish it was ;)
I think a working prototype can be built in 5-6 months, this can start generating some revenue but I don't expect that to be huge amount of money. The goal is to establish a merket share and have a stable userbase by the time ebooks really pick-up.
