That includes responses from our distributors and channel partners, among others. It would also dramatically increase the cost for people buying one or two licenses, so it would have be an 'alternate' registration means if it existed.

In addition there is the lag time between ordering and receiving the
dongle.  That could be worked around with a time expired software only
license that is good for say 10 days so you can get running right
away...  Dongles arent free and they would add a bit, likely $5-10, to
the total cost.  For 1-2 codecs not worth it.

However if you have a problem during digium off hours you can use the
generic example program I wrote (for other reasons it just appears to
work for this although I never tested it on a system with digium g729
codec installed nor did anyone else that I am aware of) will let you
change the MAC address only for the instance of asterisk that you
choose.  

This means that on a network view the system is using its real MAC addr,
for all programs except the ones you selected it would use the real MAC
addr, but for the one process you choose (my example uses ifconfig
becuase that is easy to instantly verify if it works) it will use an
alternate MAC addr.  

This is handy if you are on the other side of the world from digium and
digium is closed when your hardware fails.  The program itself was
written as an example of how to do this type of remapping, it just
appears to also work for this application.

It is my belief that this tool will not aid in piracy at all because
people that want a free g729 license will look at cisco (they run a
project which has an open g729 implementation for non-commercial
purposes) or the intel IPP stuff which is already ported to asterisk.
They are buying the digium modules to get the license since the codec is
already out there.  That means they want the licenses rather than a free
ride.  I also dont know for a fact that it works on the digium codecs,
only a hunch because there are only so many ways to get the MAC addr.

Now that you have read this far here is the link :)
