More than $87,000 worth of the virtual currency known as Bitcoin was stolen after online bandits penetrated servers belonging to Bitcoinica, prompting its operators to temporarily shutter the trading platform to contain the damage.
Friday's theft came after hackers accessed Bitcoinica's production servers and depleted its online wallet of 18,547 BTC, as individual Bitcoin units are called, company officials said in a blog post published on Friday. It said the heist affected only a small fraction of Bitcoinica's overall bitcoin deposits and that all withdrawal requests will be honored once the platform reopens.

I have been tasked with replacing a managed WiFi system for a mid-sized hotel. They have already selected Comcast to provide a 100mbps connection which unfortunately must come in at one corner of the property which I would estimate covers approximately 4-5 acres. The hotel plans to provide this service for free so there is not the need for any type of billing management systems or the like though it should be secured enough that the parking lot does not become a free WiFi hotspot. Additionally, there is no ethernet infrastructure in place. The existing APs (hidden away in proprietary encasements) seem to be connected via telephone lines and the owners have strongly indicated they would prefer that no new wiring be installed.
Have any Slashdotters implemented similar systems? Specifically, what hardware did you use and what special considerations should I take in designing this system?

I am a freelance network admin who mainly services small business clients. Over the last few months, I have been noticing that anytime I have run any type of bandwidth testing for clients with Comcast accounts, the results have been amazingly fast; with some connections, Speakeasy will report up to 15Mbps down and 4Mbps up. Of course, clients get nowhere near this performance in everyday usage.
Upon further investigation, it appears that Comcast delivers this bandwidth only for a few seconds after any new request and it is immediately throttled down. The only way to get any type of accurate estimates are to actually download and upload a significantly large file (100MB+). Doing so yields results more in line with expectations (usually about 1.2Mbps down and about 250Kbps up but it varies).
My main question is this: Is there any valid reason Comcast would front load transfers in this way, or is it merely an effort to prevent end users from being able to accurately assess their bandwidth? Also, does anybody know of other ISPs that use similar practices? This can be quite annoying when trying to determine whether a small client really needs to switch over to a T1 or if their current ISP will suffice.
