If the numbers in the meters (current workload, amount of stress and chance of emailing back) are percentages and the colours are representative of the percentage, then the 13% chance of being emailed back should be coloured red and not green to indicate the low chance of being emailed back.
It would be nice if the mouse was tilted slightly so that your wrist is not parallel to the desk. For the scroll wheel, you could put that under the thumb, i.e. on the side.
When I lived in Leeds I used to attend the Open Coffee meetings (monthly) and the BarCamps (annually), where people would talk about start-ups and start-up events, so you could target these meetings (if they are still going). I doubt you could target students directly without appearing to be spammers.
You (perhaps collectively with other roundabouters) could try holding some sort of competition for students. I am sure academics at universities would help to promote something like that to their students and you would be able to see which students are capable of building things and getting things done, i.e. which are potential hires. It could also expose students to the types of work, and the style of working, that occurs at a start-up.
