Do you think it would be fairly straight forward to use Go as a Gantt Chart like in Microsoft Project?
Yes, as far as the graphics are concerned it’s pretty easy to do. I know a number of customers have done something like that, with either JGo or GoDiagram.
Of course providing all the associated functionality for doing scheduling involves a lot of work beyond just doing the graphics.
Is there any interest in us providing this as another optional library?
I think that would be a great addon. You guys certainly know your tool better than I or most of the other developer do. There is little chance I could write this for less time/money than you would sell it for.
