We've done something like this at my previous company. The lesson I learned was that it works really well for some staff but that it goes poorly for the non-technically inclined. We ended up having a scaled down IT services for the "poets" and the techies could use their own thing. That worked well and people were happy, although security was an ongoing debate since laptops get stolen a lot and people don't tend to put encryption on anything unless you force them to. We ended up doing "spot checks" on various occasions to check if backups/etc, were up to scratch. After I left new management was too worried about security and brought it back in house (although we'd never had serious incidents). The dissatisfaction that caused among employees was huge, it's really much harder to give up freedom than if you've never had it in the first place.
