some help in technical solution

[yosi yarchi]

Hi all


I need application that will be able to collect and process inputs from 
30 (!) competitors, and will display the results very fast. The ideal 
solution could be to collect the inputs via SMS: each competitor send 
his answer, the application collect the answers (related to phone 
number) and process them. However, I can't assume that the competitors 
have mobile phones (they may be little childs...).


I thought to use 30 USB numerical keyboards as input devices, connected 
with cables to 3 hubs, connected to the computer.

However, I don't have experience with USB drivers at linux...


Is it feasible? What should be the main guidelines for the solution?


With best regards
