Does meditation increase productivity for software developers and related professions?

Is there any evidence for Buddhist meditation practices increasing productivity for software developers? Just from my own experience it seems like it does but I'm just interested into other experiences or evidence, anecdotal of otherwise. If I can try to clarify this further 1. Is there any research on this? 2. Are software companies using meditation techniques at all to help their employees? If so, what reasons do they give for this? 3. Does anyone have reasonable compelling evidence for this from their own experience? 4. If I can broaden this a little - what about related professions? - ones that require sustained concentration and maybe a little creativity. Do they use meditation techniques at all? If I can just share my motivation for asking this. I'm considering giving a lightening talk at a local software user group on this topic and I just want a broader idea of what kind of evidence there is around this kind of thing. If it seems like there is something there then I will probably throw my hat it the ring and give the talk. If it just my own personal experience I probably won't. I don't want to give the talk it it is entirely unsupported.
