Free net downloads.  Or a purchase of the Version 1 CD allows for multiple
installs to as many machines as you wish.

Differing licensing terms.  Some BSD, some GNU, some Cygnus, all OpenSource. 
See the licensing terms in the package.

The major restriction is that if _YOU_ distribute the Cygwin package then you
must be willing to provide a copy of the source.
