Are you saying that all of these dongles are identical pieces of hardware, all for the same software (software protection)?
What exactly do you mean by floating? I haven't heard that term before. Do the dongles always remain connected to these computers, or are you saying that they might get swapped with other dongles/computers?
Is your goal simply to physically move these USB dongles, i.e. to a server room / server closet?
FYI, AnywhereUSBs function the same as standard USB hubs, except for 2 major exceptions:
1. They connect to Windows-based computers through the network instead of a USB cable. This allows USB devices to be much further away from the computer(s).
2. With certain model AnywhereUSBs that have the MHC (Multi-Host Connection) feature, the USB ports can be split up, so that different computers can connect to certain USB ports. Note that USB ports/devices cannot be shared - in other words, multiple computers cannot be connected to the same USB port(s) at the same point in time.
