Technically hard isn't the only kind of hard. This is one of those spaces where a lot of people have a lot of complicated processes, and they will be pissed if you don't support their particular approaches. Writing the code wouldn't scare me off this market, but the work to discover the full extent of the domain and the user needs would sure give me pause.

Seems a bit of a moot point, though, as I'd expect most customers here see this as something they want to just work without problems, so they'll be heavily biased toward known major brands. It's sort of like the space for cloud computing in that way. Usually, my most important criterion for a cloud vendor is that their shit will stay up forever, because my whole goal is to not think about a bunch of things.
