Meru's gear, back when they were only doing "b" was interesting. Now, when it's combined with 802.11n's MIMO, it makes other vendors' networks just look bad. Seriously, if you're looking to deploy a wireless network that will host streaming audio or video, Meru is the best choice (technically or financially). (This was my opinion 5 years ago and it hasn't changed.)
If the Road Show is coming anywhere near you, I recommend signing up for it. You'll get to meet a number of engineers who've been around the block a few times and the food is darned good also (the training (and the food) was at the Occidental Restaurant in DC, near the White House). I believe that it was in the Monument Room that the training was held.
