I'm starting a research project looking at storing small amounts i.e. up to 100k of arbitrary data (encrypted private data) within a blockchain and think multichain could be a good API choice. I guess follwing in the spirit of Namecoin but with arbitrary binary data blobs not DNS records. But I don't see how this could be achieved in the multichain blocks at least from the simple examples posted on the multichain.com site.
a) Is this actually possible with multichain?
b) If so is there an example anywhere or can someone point me in the right direction?
