To be responsible, here's my source for this information:
http://boardgamegeek.com/article/7992464#7992464In the article, he mentions that he would be willing to give the source to someone else who would maintain the app, and he is OK with that person open-sourcing the code.
I spent a few hours last night trying to get the app developer tools set up on my home computer to no avail. I feel like I was really close to getting it to work, but I eventually got to the point where I gave up. I wasn't exactly hoping to develop something awesome and robust here, I was just gonna hack something together that none of you guys would probably want to use.
If I could see the source and it looked like something I could work with, AND if I could get a development environment set up (I might consider trying again on a free weekend), I might consider maintaining the app myself. I will not be offended if someone else wants to do it.
Perhaps we can link Mr. (I checked) Jessurun to this thread if we get enough people who like his app, and maybe he would consider releasing the source to us.
I shall check into this "Dominion Card Selector" since it looks like it has become free since I last checked for apps. Maybe this is the answer to our questions, since it seems like it's been updated recently.
