I have not tried this per se, but I don't see what's stopping you from having as many Cygwins installed as you want. Now, I'm not saying that you could USE more than one at a time, due to the fact that only a single Cygwin1.dll can be active at any given time -- and I wouldn't expect this to change before the heat death of the universe. But the only thing that Cygwin touches outside of its install path is the mount table in the registry, and this is easily removed/replaced with mount and umount. So, if I were doing this, I would install Cygwin #1 to \cygwin, then "mount -m > mounts.txt ; umount -A", then install Cygwin #2 to \cygwin-b or whatever, and so on. To switch between them just unmount everything and remount the other one. Additionally, these vendors must have shipped you source to everything compiled against Cygwin1.dll, or else they are in violation of the GPL. So, you should be able to recompile everything against the latest DLL, and just use a single installation. The exception is if they purchased the Cygwin buy-out license from Redhat.
