I would only recommend that for the Proof of concept. You will definitely need your infrastructure team involved when it comes to installing the appliance. And you need an executive to remove roadblocks and help make things happen once you get moving.
With that said, I do understand that IT infrastructure can get a little butt hurt about installing appliances. Like I said, I've been doing tech for 30 years now and one trend I have noticed is that a lot of IT departments have drifted away from the customer centered mindset they had when I first started out. This is not true for all companies but for a huge number of them, the marginal IT staff are more worried about the appearance that they are geniuses and maintaining control. Installing an appliance like this strikes fear into their hearts on both fronts and you need to be mindful of their inflated and fragile egos.
Let me give you an example. I did some work for a fortune 100 company that largely outsourced its IT to India. They still have large IT departments in the states which tend to be more useful than their Indian counterparts who play all sorts of games to close "tickets" without ever addressing problems. I had an Excel based BI solution that needed to be rolled out to sales people. IT in their infinite wisdom opened the gates for people to choose Apple laptops but made anyone ordering one sign an agreement that basically said IT is not responsible if shit doesn't work.
They had a lot of issues with internal sites that required IE so the solution was to make IE available through Citrix. OK, that's cool. They figured that one out before rolling out the MacBooks. When it came to a custom Excel solution they were not going to add Excel to the Citrix box. When asked why not, they claimed licensing costs of Excel. After looking into that I discovered that there would be no licensing issue at all and was able to prove it. Then it became a "security" issue. When pressed on the nature of the security issue, they came up with a lot of doublespeak that amounted to a giant heaping pile of bullshit. It would have taken less than an hour to publish Excel on Citrix.
They spent more time arguing against adding Excel to Citrix than it would have taken to just add the damned thing.
The upshot of all this is people expect a lot less from IT now and they suffer needlessly and waste a shitload of money because IT doesn't give a damn about their customers anymore. They are not in the problem solving business and they just want you(the business user) to go away unless it's something they feel like playing with.
This is one of the reasons I love doing consulting work. I like to help people, I like to automate and I want to make the computers do the mindless work, rather than people. IT, too often, gets in the way and causes more inefficiencies. In the case of this particular client, they have to hire more staff to manually deal with data and processes that they cannot get IT to automate.
