It helps of course that the bitcoinj networking/ object model is also used by Andreas as you note. Greg: I think Mike has squashed the deadlocking problems with reentrant locks (primarily in the Wallet). I haven't seen one in at least a month. We discussed proxy support on the bitcoinj mailing list a while ago and at the time the stumbling block was the Java library used for the networking (Netty) did not support it. Mike or Miron would know better than I if this is still the case. Change address behaviour will improve significantly when HD wallet support goes into multibit/ bitcoinj (I am hoping to get my bit done over the summer). Matija Mazi has been working on a Java impl of HD wallets so it is coming down the pipe but there is a lot to do yet. Connections out from MultiBit are: + 4 bitcoind nodes on port 8333 + multibit.org (188.138.113.201) for help, current version info (and probably more in future) + the currency ticker will make HTTP gets to the source of whichever exchange(s) you have set up e.g MtGox, CampBX. This calls should disappear if you switch the currency conversion and ticker off. I think that is all the connections out I make. Mainly due to the exchanges abruptly changing their APIs and breaking things we are planning to put in intermediate "Exchange Data Provider" servers. Tim Molter is working on this in his XChange project. That will enable us to patch the server when things change and the multibits in the field won't be affected. There will probably be a couple of these initially for redundancy. Alex: Yes I think most users migrate to blockchain.info or, more recently coinbase.com. They are both good wallets but I'd like to keep Bitcoin as P2P as possible. Luke-Jr I think you are right here on the number of full nodes versus SPV nodes. I don't think we even know yet what are the working ratios of full nodes to SPV nodes. I haven't seen anybody do any analysis on this. I doubt multibit will ever participate in the Bitcoin network other than as an SPV client. All the optimisation is to reduce data traffic - it is effectively a mobile wallet that happens to live on a desktop. It is not really intended to be more than "a wallet for regular people to store and spend their bitcoin". In English the nomenclature for direction of the transactions is: "Sent to" and "Received with". To be honest I haven't transliterated the localisation files to check other language packs but the localisers are pretty good in my experience.
