I don not see such big risk with multiple installations.
Basic rules appliy:
- separate PATH between the diffent installations.
 defining CYGWIN_NOWINPATH help on it
- don't mix services as they will be called all in the same way by
  the different installation.

Usually if Virtual Machines are possible there are less motives to use cygwin;
people developing for cygwin are of course the exception.
