agreed - also as an irish user i can receive alerts via sms which twitter currently doesn't provide!!

i must third this option, the two seem to go hand-in-hand.

what should the implementation be? bidirectional?

ie, it seems obvious that if I check-in via bkite to a location associated with a task that I should somehow be alerted of that fact (email, sms, whatever).

however, what about completing a task on rtm first? if I complete a task on rtm that has a location associated with it (ie, my local grocery store) should I get an sms from bkite asking me if I want to check-in there and update my position?

let me know your thoughts.

Any sort of integration would be awesome, but turqy's second idea is particularly neat. Maybe look into Fire Eagle too?
