Re:  "Highlander"

Greatest movie ever.

re:  "Webservers"

This is a good point, but a closer inspection of the webservers shows that
the situation is quite different from Accumulo vs. HBase.

Apache WS is in implemented in C, and Tomcat is implemented in Java.


Accumulo is, effectively, trying to be "Timdog" - by being the 3rd
webserver that is just like Tomcat, and in fact borrows some of the code
from Tomcat (another issue, but point of fact true) and also claims to
have a "community relationship" with Tomcat (which nobody in the HBase
community has seen).
