I guess the question is, what is the point? We can already take any portion of our pay and purchase bitcoins with it, no need to set up direct deposit and all that.
Perhaps more importantly, bitcoin is simply too unstable for this at this time. Speculating in bitcoin is all well and good, but I don't know that too many people want to gamble say, their next mortage payment on it.
where i live i can pay my rent in bitcoin, food and other things. so having my pay directly converted to btc has its advantages.
no one is saying that it should b something everyone uses. i think only 1% of people (well under 8k people out of the known 800k bitcoiners would find it useful)
but im more concerned with if they are legit with all the T's crossed and i's dotted in regards to handing peoples bank deposits.
after all as you say it could be someones mortgage or rent payment they are messing with if they suddenly had to 'close shop'
