We've seen some arguments for and against opening drivers. I'd like to point out that ESR has written about this as an afterword to his essay "The Magic Cauldron", which you can read here: Afterword: Why Closing a Driver Loses Its Vendor Money http://www.catb.org/~esr/writings/cathedral-bazaar/magic-cauldron/ar01s18.html FWIW. -- De gustibus non disputandum est.
