Looks interesting, if it does all you say then you have a great product.
One comment on the design, it might be safer to use barb fittings on the valve internally as some of those pipes look like they bend significantly on exit from the Festo's and that is not ideal - a barb would be more reliable and probably give you a little more room - and cheaper too
Please post a link to Skynet as its not easy to find via a Google search.....
