    Not sure if its possible but I would like to know if one can create Lion USB installer and Windows 7 USB installer on one 16GB USB thumb drive?

    Both of them take around 8GB and I have one USB drive that I want to use to keep the installers on

    Absolutely! Use Disk Utility to split the drive into two partitions, the use the restore functionality to burn the images to the drive.

    Just tried it. Worked great for Lion but not sure if it worked for Windows 7

    I checked in Startup disk selection and I see lion in there but don't see windows 7 option.

    I did a DD of windows 7 iso to disk7s3 partition.
    here is what diskutil list shows:

       #:                       TYPE NAME                    SIZE       IDENTIFIER
       0:      GUID_partition_scheme                        *16.2 GB    disk7
       1:                        EFI                         209.7 MB   disk7s1
       2:                  Apple_HFS Mac OS X Install ESD    8.1 GB     disk7s2
       3:       Microsoft Basic Data                         7.8 GB     disk7s3

    Only way I ever get Windows USB sticks working is from cmd in Windows

    Or you could use microsoft's own USB tool "Windows 7 USB/DVD download tool" here.
    It creates a bootable windows installer usb stick :) .
