As many comments say, with the right tweaks input is sortable - everything from the laser projected keyboard on a desk to the USB or bluetooth rollable keyboards, or a reworking of the aging Cykey ( http://www.bellaire.demon.co.uk/index.html ), the abandoned Twiddler ( http://www.handykey.com/ ) or the vaporware/endless prototype Senseboard ( http://www.senseboard.com/ ). Can't say I'm a fan of the thumboard, but... if the code was more like txt spk than Java it might be tolerable.
Also, output is achievable - either in small on screen, with a pocket projector up to around VGA on a nearby surface, or a head mounted display like the Vuzix ( no need to go all Steve Mann and use a head-mounted CRT these days http://wearcam.org/stevewearcomp6cropgrey.gif ), or a pluggable external small LCD might work.
Most of this is existing kit you could put together.
I wonder, though, if the best help would be a programming language that jointly minimizes typing, screen use, and encourages think-before-you-code. Sounds a bit like the brief for Arc to me.
So I think the sticking point is somewhat hardware, but mostly software - what software support would it need to make it usable? What auto-sync to the cloud dropbox style? What create-and-publish-in-one package like wordpress, twitter, posterous mobile clients?
So - what about a kind of twitter/posterous for code? Write/run and then upload for the world.
Also, make the normal phone/PDA functions simple and scriptable - with cron and with plugins/hooks/callbacks/events.
