You know if you made a sever jar you could run your own server? And there is a second european test server on the G+ group? I hope you're in the 0.8.* series. Even though the ars bugs are rough, Thaumic Tinkerer is a force to be reckoned with.
If I had enough time to do some beta testing, I'd be tempted to submit my own application. Sadly, with my own mod pack I'm working on updating and beta-testing the 'dev' version, I don't really have the time. I'm generally running 1-2 versions 'newer' than the release version of ShneekeyCraft and bugfixing on the fly. I'm also still trying to find a way to automate berry bushes. Harvester functionality broke, Forestry multiblock farms won't recognize them, fruit pickers won't recognize them... golems work, but golems aren't in my mod pack.
Of course, once I can get berries to work, there will be the concern about oreberry farms producing a viable quantity of metals...
Oh, and Shoop. We're about to get yet more building blocks with DartCraft, and Ethereal Glass exists and looks a lot like a forcefield.
Not a fan of Dartcraft personally, but the Ethereal Glass is awesome. Basically, players can pass, but mobs can't. So it is perfect for external doors on bases.
