comment Same number of clients - multiple WAPs vs Single WAP
In basic terms, an RF channel can only have one 802.11 device communicating on it at a time in the same area. As such, it is a finite resource that is shared among all devices. Air time generally refers to the channel utilization, either in total, in use by a device (or group of devices), or type of traffic and is often used when trying to make more efficient use of the RF medium.

comment How can I avoid Mac OS X temporarily setting its IP in the “link-local” range (169.254.x.x) at boot time?
@Pickles, the problem with falling back to its "last-good" address is that the last address may now be in use by another device and then cause an IP conflict on the network, which is potentially far worse.

So, to paraphrase your answer and comment, using the reserved addresses is a violation and using a manual assignment from the generated range is a violation. So then the answer should be "No, this is a bad idea. You need to find a better solution." If people were to just ignore the standards and specifications when they are inconvenienced by them, then the standardization, inter-operation, and the whole foundation of networking/the Internet are all at risk..

Why would you suggest using the two ranges that IANA has reserved for future use? That seems to be bad advice in case the IANA chooses to make use of those reserved ranges for some reason.

If they are only used to communicate from service to service within the same host, is there any reason you wouldn't use a loopback address?

Unfortunately, this doesn't have great documentation anywhere I have found, but you can find details from the Cisco Support forums such as this post here.

Even better than TFTP would be USB, which I did suggest in my original comment on NE (before you deleted and moved it here). Works on 2960S switches quite well. However, to do TFTP from ROMMON, you configure the IP information in ROMMON.

comment How to setup a VLAN that spans across both Hp 1810g and hp 2920G
It would help if you provided the configuration of your ports. However, for your new VLAN are the ports configured to use that VLAN untagged rather than your first VLAN?

comment Point of Shared Secrets on RADIUS Servers over a Cisco Switch
@ArranCudbard-Bell, the sentence started with "For many RADIUS messages." So I didn't claim it did so for all of them, nor did I say it would protect from the NAS or RADIUS from processing the message. For completeness, RADIUS servers will also drop based on the response authenticator when acting as a proxy.

comment Point of Shared Secrets on RADIUS Servers over a Cisco Switch
@ArranCudbard-Bell, if you check RFC 2865, you will find that any message with a response authenticator provide both 1 and 2. This would include at least Access-Accept, Access-Reject, and Access-Challenge messages. The response authenticator is a one way hash that uses a number of pieces of information for the input, including (but not limited to) the RADIUS response attributes and the shared secret.

comment adding a third subnet on the same router
What are you trying to accomplish with this new subnet? Are you assigning the new IP addresses directly to server or is there a firewall or other device doing NAT? Maybe a network diagram would help?
