The short answer: I can get ca. 69ms to Florida from Oregon.

The long answer: From OGI's network, connected to the wider net both 
via Internet/2 and a decent AT&T pipe, here are some ping times (ping 
-q -c 4 HOSTNAME):

West coast:

* limestone.uorgon.edu       3.855 ms
* www3.cac.washington.edu    4.826 ms

Mountain west:

* cujo.colorado.edu         31.426 ms
* ns.utah.edu               42.293 ms


* nss.nts.umn.edu           75.623 ms
* hm.missouri.edu           45.651 ms

Now, on to the east coast:

* www.mit.edu               79.749 ms
* kedu.cc.columbia.edu      83.845 ms
* dukedns1.netcom.duke.edu  87.162 ms
* serv1.net.yale.edu        84.135 ms
* dns1.fsu.edu              68.605 ms
* nameit.ume.maine.edu      93.206 ms
