Hi Jason, I don't know what temperature range you want to sense. I have had success using I-Button temperature sensors directly on a USB RS232 connector. With this set up you can have multiple sensors on one line as each sensor has a unique address. The software I used for this was from a book Linux Toys by Christopher Negus and Chuck Wolber.
