Dig..
for what it's worth..I work in same Office complex as "World Headquarters"- have popped on over on occasion to check stuff out etc..sometimes there will be some engineers on computers that will chat, sometimes I imagine the the engineers are getting their hands dirty on testing of the IVT off site, and the Gleasman's and the CXO guys are I think are often off premises...traveling, in meetings etc.It isn't unusual I don't think then for the doors to be locked for a few days and no answers to emails etc..I have sent a few.. sometimes Jim responds, sometimes he responds to say he can't respond, and sometimes nothing but silence..Is this unusual for start up???don't know but this is run extremely lean which I guess ain't such a bad thing til there is something with some $$$ attached to it..For What it's worth...I could be all wet- often am..
