Sorry to hear this, but I think that the customized browser is basically DOA. It's hard enough to get people to update their main browser as it is. Better to build whatever you have in mind within a conventional browser.
As an end user technology it was always DOA except in very nerdy niche's. As a delivery technology I think we'll see it around for a long time to come. Users clamour for "native" apps, this is a cheap (fake) way to give it to them.
I didn't really find anything on it. Nothing that could cause the company any damage. I don't really remember because one of the first things I did was to throw Ubuntu on it.
