Welcome! 😎
RC5 might be a better project for a laptop in use than SETI. If you run out of SETI WUs, which are also large, SETI just quits. But if you run out of RC5 WUs, it does random blocks which have about a 75% chance of being counted. Also, you can set RC5 up to connect whenever it detects a modem connection.
'Course if the laptops are stationary and can automatically connect to the net, SETI would do just fine. 🙂
