I've also followed NSF since last summer.
There has been a change recently, in that the DIY posters have not come up with real data for a while. The Travellers 8mN force with just under 100W power is a very significant number, but I think folk are right to be skeptical as there is no real report on the experimental data. SeeShells is rebuilding after she burnt out part of her first build when she was convinced she saw an effect. Rfmwguy thinks he saw something and published his data on the blog. Looking at the data I don't think the 177 micro-Newtons he measured was out of the noise on his experiment. He is refining his setup to try and produce conclusive data.
Provoked by conversations on NSF, I took a look at the last ten years of so company filings from SPR, Shawyer's company. The accounts are consistent with Shawyers story that SPR worked with Boeing for a period ending mid-2011. Previously it survived on grants and shareholder loans. SPR also made some money in the last financial year filed, ending March 2015, consistent with a small IP or consultancy revenue stream. It is making no capital investments so one can deduce that any real development work, if it exists, is being done elsewhere.
My take-away was that Shawyer has over the last ten years had ample time and money to determine whether the EMdrive effect is real or not. Judging by the Horizon programme on the BBC recently, he's also had ample physical resources. To me the situation is pretty black-and-white: it either works, or he is delusional/crooked.
The "delusional/crooked" hypothesis takes a hit from the recent pronouncements from Cannae, and the fact that serious people at NASA still repeat that "the anomalous force remains".
It's also worth bearing in mind that if the effect is real the stakes may be very, very big. Expect openness and straight talking all round...
