I considered coding my own, but once I started writing a spec, I realized it was way bigger than it seemed (that happens a lot), because of all the features I would want. And it's just not worth it for our business, even if done in ColdFusion which is super fast. I'm a little nervous about Trellis's support/commitment and all, but if we have to switch someday, it won't be as big a deal as it would (will) be for you guys.
