Yes the the USB key may accessed simultaneously by many computers according to the license (one ore more computers). Think about the computer with the dongle as a host and others are guests using the same device. The protected software dont check the dongle every second. I told you, I use the HASP Emulator and it read from the Windows registry how may keys you own.
This is the key exported form the registry but some fields are scrambled with x and y charactes. If the emulator is installed and you own the reg file it's enough to duble click it. I this case the key include the emulator and two softs (Dump\xxxx__ and Dump\yyyy___).
