I miss mozilla's XUL language (and XBL!), those were awesome.
XUL was beastly back then though.
Out of curiosity, what does that app do to convince people to jump through such hoops? Would you mind sending a link to it?
There are still 3 companies that use it (since 2008), so their employees don't have a choice really. The app does a lot, so to stop using it the companies would need to hire and migrate to 3-4 other services. I reckon SAP and the kind could do everything as well, but these companies are too small for that.
There isn't a website or anything anymore for me to show, and I haven't been involved in it for over 10 years.

Good old time.
