Actually, the last 3-4 versions have all supported scripting and dependencies. There's currently a nasty parser overflow because the setup.ini got too big, but I've just fixed this and am committing a CVS fix asap. Certainly I encourage experimentation and am happy to discuss what can be done. The official setup.exe mailing list is cygwin-apps(at)cygwin(dot)com(dot) Currently there are ~4-5 folk actively contributing setup.exe code, so things that take someones interest happen fairly quickly.

The KDE on cygwin group use this approach (they distribute binaries via a setup.ini site, but don't distribute setup.exe at all). You simply add a user URL to setup.exe when you run it, and it picks up your package, merges it into the list, and will install any needed packages from any other site as listed by your 'requires:' statement.

Yes. Also setup supports pre-removal scripts, to allow tidying things up.
