I guess someone has mentioned to their students this April Fools Day RFC about a new "IP over Pigeon" communication standard? <a href="http://tools.ietf.org/html/rfc1149">http://tools.ietf.org/html/rfc1149</a><br>
<br>In many cases pigeon-based data transfer is faster than ADSL eg <a href="http://www.notes.co.il/benbasat/5240.asp">http://www.notes.co.il/benbasat/5240.asp</a> , <a href="http://technologyexpert.blogspot.com/2009/09/pigeon-beats-internet-in-data-transfer.html">http://technologyexpert.blogspot.com/2009/09/pigeon-beats-internet-in-data-transfer.html</a><br>

Wow, if I tug on a piece of string I can probably transmit at the rate of 4 bps, if I could line up 16 clones with strings in parallel, I could probably reach this speed. The real bottleneck is my brain that operates at about one flop per second (with no check digit you can expect oodles of errors) a system for caching the string tugs and adding a user interface with some empty tin cans.<br>

<div><font size="2" face="Arial">So sorry to see the demise of this wonderful device
- I assume Mark that you meant 56Kbps, 56bps would be a tad slow even by the
standards of yester-year. Gee I am getting old! How many of you "out there"
started with 300bps modems?</font></div>

<div><font size="2" face="Arial">I still have the delight of using a 56Kbps modem
for access when down at Yinnar. It works well although a tad slowly, especially
when people send you emails with photos with file sizes of 1-4 MB.</font></div>

<div><font size="2" face="Arial">Oversize as in the example of emails with photo
attachments. Used to be that I would resize photos to 640x480, when that was the
normal screen resolution, and save as jpg files at 70% quality to make sure that
the files I sent were of a reasonable size. Not so any more. My rels take photos
on their 10MB cameras and send them to me as high quality jpegs. I can't
even view them directly onscreen as they are far too big. I don't want to
print out high quality A4 prints from all these photos, so why send them to me
at this size?</font></div>

interesting to see protocols are back in the Key Knowledge for networking
