I was excited when I saw your indoor SDK, but it's too simplistic and not realistic enough for the production apps we have and are building (walking around and mapping every single room in a hospital is untenable).
I don't mean to bash your company at all here, so I'm sorry if this comes off that way. I also found that almost all clients scoff at ~$33/beacon when you're pitching something in the 10,000 beacon range. Even then, for $30/beacon I can get ones that run off the wall circuit and last until that's off (for all intents and purposes, longer than 5 years).
Obviously at 10,000 beacons we're talking enterprise pricing, but even if you were to get that to around $5 that's still too much for what's essentially a CR2032 battery and a tiny radio chip.
I'm excited to see where Estimote takes beacons though, since they seem to be doing the most R&D type pushes with this technology compared to the other manufacturers.
