We're building a way for others to build and take ownership of their Channels: https://ifttt.com/platform Hobby or personal Channels are an interesting idea!

A generic REST Endpoint action and a generic Webhook trigger would pretty much do it, but I can imagine why you wouldn't want to offer that.

Would pubnub or dweet.io work for you?

No, they're not really. We're building Smart IR Remote (universal remote android app) and AnyMote (hardware, now on kickstarter), and we applied on IFTTT's link over a month ago, without any reply. Didn't even get back to us.

http://dweet.io can give you a rest endpoint. It is very easy and open source

Correct me if I'm wrong, but Dweet doesn't really solve the use case of "I want to connect my hobby app with existing third-party APIs without having to do manual integrations". It's great for home IoT setups, sure, but that's not the main use case I care about.

This, dweet is a nice solution here.
