I did a proof of concept with Trigger and I must say that it's a pleasure to work with. But in the end, we still decided to go with Phonegap because of two issues :

1) What happen if Trigger.io close their door? 2) Ability to add native features if required

From what I'm reading, #2 is not an issue anymore, but what about #1 ? I understand that for any commercial product, but usually, if a company close their door, you can still use the product (but without any update). What about Trigger? Would all my apps developed with it still work after they shutdown?
