How hard would it be to add SPV support to Armory?

This way, those of us who don't really need a full node could still use all the other great features that Armory provides without having to download the whole blockchain. This would be wonderful.

I would think imagine that it can be connected to an spv node since armory's full node functionality is from bitcoin core. If you had an spv node that acted like bitcoin core, I think it should work.

Currently Armory expects access to raw block data as saved by Core, via a folder path. 0.93 expects full history so it can't deal with anything short of the entire blockchain. 0.94 could run off the UTXO set, if there is a node implementation that offers that. You won't have the history, but you will see your balance and be able to spend.

I am in the process of migrating the database interface from SWIG to a plain HTTP, so that upcoming change will allow you to connect several lite clients to a single server. Since it's HTTP, we could even have a HTML GUI in the future.
