I'm happy to continue to see activity ... thanks gjhiggins! The OP_RETURN inclusion was something I also was interested in, but considered it a bit early to propose it.

OP_RETURN would enable Slimcoin to use asset libraries like OpenAssets or even the brand new (alpha still) PeerAssets - the latter having the advantage to come from the Peercoin community, so it should be easy to port it to SLM. PeerAssets probably would also make possible a decentralized form of cross-blockchain trading.

I'm still struggling a bit with the 0.4 Linux version - once I provide it an advanced blockchain it syncs without problems but it fails to download it from the start - the problems beginning at block 530. It's possible that it's a configuration problem on (both of) my systems (although they are different Linux distributions).
