Yes you can. The email address to send enquiries to at BeeHive Internet can be found in the file dgd/doc/Commercial in the DGD distribution.
You may have heard of iChat Inc -- later renamed to Acuity Corporation and then turned into a subsidiary of Quintus Corporation -- in this respect, this would be because the commercial rights to DGD were licenced exclusively to that company from January 1996 until March 2001.
As an aside, the iChat.com domain is now owned by Apple and that company can now be found at globalchat.com. Such a confusing world we live in.
