Good luck for sure, but browsing their compatibility matrix, it looks like they are a LONG way off. By the looks of it, they have mostly read compatibility with little write capabilities (no alter table, for example).
There isn't a long term roadmap, or anything like that. I got pretty excited when I saw the results, though. It's less about the number of github stars - who the hell cares about those - but the contributors. Limbo already has a very nice list of contributors, which led me to believe there is something here!
The first 90% is easy, it's the second 90% that is very hard.
In my experience the 10% that doesn't get done is the 10% that people don't care too much about it anyway.
