Disable sleep in clamshell - Mavericks apps?

[MyAppleWorld]

there is the odd occasion when i went to move to a different room, especially walking up/down stairs. I like to do this in clamshell mode but fed up of any downloads stopping etc.

what is the solution?

also i understand that 'sleep' mode kicks in 3 hours into clamshell mode - can this be made quicker?

One quick tip. DON"T put it on a bed or couch, it gets really hot when in clamshell mode. Use a vertical stand(book arc) if you are looking forward to do so.
