You need to so a simple calculation. Is the increased productivity/good will you will get by allowing developers to pick worth more then enforcing a heterogeneous environment and loosing some productivity. There are nearly always ways to work around compatibility differences. Sure you need word to talk to banks/accountants but most developers will be more then happy to work within a wiki. They have no need for Office (although sometimes Excel is worth having as a developer but open office will suffice for that) The cost of finding these alternative routes is minimal especially if you find good developers who will no doubt have experience in this sort of thing. In fact you might create a more nimble work space if developers are used to accommodating others and are more open to change. Good luck and be sure to let us all know how it goes :)
