Winmac (http://winmac.emuunlim.com/) is a program that gives Windows users a MacOS like menu bar. I would basically like to see it go portable. I tried by simply install it to my flash drive, but it unloaded some files to C:WINDOWS\system32\. Hopefully my school doesn't notice. I'm not sure if it is open source, but I or someone else could send them an email to ask for either a portable version or he source, or at the very least see if they respond.
Edit: On a side note, what happened to he portable Mini vMac?
