Hi there. My apologies for not getting back to you sooner; I've been
traveling lately, and catching up on e-mail has been a sometime thing. :-)
Well, as the license included in all of the source files states:
* Export of this software from the United States of America may
* require a specific license from the United States Government.
* It is the responsibility of any person or organization contemplating
* export to obtain such a license before exporting.
*
* WITHIN THAT CONSTRAINT, permission to use, copy, modify, and
* distribute this software and its documentation for any purpose and
* without fee is hereby granted, provided that the above copyright
* notice appear in all copies and that both that copyright notice and
* this permission notice appear in supporting documentation, and that
* the name of M.I.T. not be used in advertising or publicity pertaining
* to distribution of the software without specific, written prior
* permission. M.I.T. makes no representations about the suitability of
* this software for any purpose. It is provided "as is" without express
* or implied warranty.
So no, there's no need to pay MIT any money, or do anything else. If
you use the name "Kerberos" in your product name, you need to get
permission to do so from MIT, since "Kerberos" is trademarked. (You
can, of course, use Kerberos in your advertising copy and in your
documentation without first asking permission, as long as the trademark
is properly acknowledged.)
Some companies will give us courtesy copies of the product, and send us
back any bug fixes that they make while incorporating Kerberos into
their product. This is not necessary, but it is a nice gesture. It
makes it that much more likely that we will speak well of the product,
if we know it exists and we know what it does. :-) Contributing bug
fixes to the Kerberos core back to MIT is part of being a good network
citizen, as Kerberos is a product of many outside of MIT, all
contributing towards making Kerberos a better code base for all. (Much
like the X11 source tree, for example.)
I hope this answers your questions! If you have any others, please feel
free to call or write.
