Does anybody here manage a Xirrus wireless solution? For an enterprise solution would Xirrus be better than Cisco in terms of coverage and cost?

We were going to test Meru but the AP's were pretty expensive and their "virtual"-cell design has some drawbacks that I'm sure their website or reps don't talk about. Of course every vendor we tested had some kind of downside, to be sure.
Of all the vendors we tested, no vendor had to worry about the 1/6/11 "crap" as they all did adaptive RF, managed automatically by the controller.
APs + licenses are $1000/each for AP311 (ABGN). The only "downside" they don't mention is that with Virtual Port turned on the clients do not have location awareness. That is, instead of the client choosing which AP to roam to, the controller does it for them. It after all knows more about the environment and can do stuff like load balance the APs because of this. If you need the location feature, there will be a feature called Virtual Cell Overflow in 4.2 which allows you turn present a non-virtual cell network on a given ESS if necessary.
The other nice thing about a single channel architecture is that you can crank the power all the way up - this means far less APs. We cover ~400K sq/ft. with 100 access points. In most every area several APs can go down and not lose coverage.
And don't believe what other vendors (Cisco) tell you about virtual cell/port until you see a demo for yourself. Cisco is none too happy that technology is patented. Remember that wifi essentially is a hub architecture if you leave the intelligence to the clients (see CSMA/CA). When the controller handles exactly who can talk when, this eliminates any collision domain (virtual port).

And no I don't work or resell Meru - just a happy customer. The founder of the company even came to our site to get feedback and look for suggestions - how's that for customer service!
A wise man once told me "No one ever got fired for purchasing Cisco" ... It has worked well for me so far.
