My company uses an internal version of Bugzilla which has been fairly heavily modified. Several fields have been added to the BZ DB's "bugs" table, and to a few other tables as well. The most relevant changes:
-The "bugs.version" value has been changed from an enumerated value to a string (VARCHAR) in the DB spec.
-The usage of the milestones table has changed such that there can be more than one milestone with the same name, so long as they refer to different products.
Certain staff members in my company have long been interested in having a desktop-application interface to Bugzilla, and we might be interested in your product. However, I'm concerned that your product may not work with our modifications.
We're also interested in the option of altering the desktop tool itself. I see that you endorse Open Source projects; but is there any option for a lincensee to have access to the entire Deskzilla source code?
As Bugzilla is open-source and easily modified, I'm sure my company would not be the only one with a modified version of Bugzilla, but with interest in using Deskzilla nonetheless. I hope you can point out some of the issues involved, and whether there's any possibility for the "tinkerers" among us to have (licensed) access to the source code of your very impressive application.
