Well, now that the ZigBee Alliance has finally released a useable specification (the PRO), Airbee's PRs can finally have the revenue to back them up.
Proof of upcoming revenues is the recent 10-K that announced recepit of $200,000 from NXP...which is a spinoff of Philips Electronics who still owns apprx 20% of NXP.
Many more PRs with potential revenue coming down the road.
