IMHO, vendors like Dust Network, Synapse, and Greenpeak (just to name a few) are more eager to sell their products to larger cooperation. Furthermore, their modules are geared towards single chip (or single module) solution whereby the are promoting the use of the their software to configure and program. What I'm disappointed is at times, the sales guy always ask questions like how much is your consumption per year and how big is your company, etc. No doubt, the Synapse products are awesome products, I just wish that they have a wider distribution network like the XBee. :-[
