Assurance Contracts Redux

[jcrubino]

Anything that depends on bitcoins RPC mechanism means you need a full node running, and that will become less and less common in future, especially for end users.

Is there anyway around this for lightweight clients?
Can blockchain, electrum, multibit, or spv based servers be queried for the necessary rpc calls, inputs and outputs?

I have only started to look into assurance contract development so my understanding is very much incomplete.
