Get your taxes done using TurboTax

If you install Home & Business, and Business on one machine, will that limit you to 5 e-files in total?  Or will you still have 5 e-files for each product?  I need to buy Home & Business, and Business also, but I was going to install them on separate machines, because I am afraid that it will limit me to 5 e-files total if I put them both on the same machine.   I had heard that the way they limit the e-files is that they use the serial number of the computer to determine how many e-files have been sent from that machine.  Have you heard anything like that?
