Blow the exhaust through a row of old car radiators? Pump the water
towards the engine to get the hottest water out. .

I purchased a couple of these to replace my PC based household
file/web/email/ftp/HA/fax/voice/NTP server and to reduce my 24x7
household power consumption.

If you wait long enough Pogoplug v2's can be found on amazon for
$8ea.. (The price changes every week or so.. sometimes it goes up..
sometimes down+ free shipping.. wait for the right price..)..
(Amazon.com product link shortened)
1.2 Ghz ARM cpu with memory management, 256MB ram, 512MB flash.
4x USB 2.0 ports, 1x 10/100Mb/1Gb ethernet port. runs 2.6 linux..
Draws about 3.6 watts @ idle with ethernet connected @100Mb & 2Gb usb
flash. The single Internal logic board run's off of a single rail
+5V switching power supply, so it's fairly easy to convert into pure
DC unit or add in a small UPS/battery circuit.

A fair bit of 3rd party linux activity is centered around this
product. I.E. Replace firmware.. boot your own customized Linux.

Forgive me if this is stupid question, but this product is entirely new to me.
Will the USB ports on the Pogoplug support devices other than drives?
Specifically, I find MagicJack tempting, but have no desire to run my 100-Watt
desktop 24/7 just to keep my phones alive.

Yes they are generic USB 2.0 ports.
If you are running you own linux kernel..
For example.. Besides using some USB 2.0 based mass storage devices,
I plan on running one or more HDTV tuners dongles, a 801.11g wireless
adapter, Bluetooth adapter, Opto-isolated 1-wire interface, and a VOIP
phone interface.
Naturally, I expect overall power requirements to climb a bit when
everything is plugged in.

Problem with MagicJack.. is that it's currently written for Windose
and x86 processors. They claim it will be ported to linux soon, but
when and which versions?

How about an older laptop on its AC adapter? They sell pretty cheap
when the batteries are dead. This Latitude draws 20-25W at idle and my
older Armadas go as low as 14W.
