but that still depends on being able to download electrum no if you didn't save the source If it does maybe make the wallet into some kind or encrypted p2p for downloading the wallet So making electrum into a clone of the original wallet but instead of sharing the blockchain it shares the electrum wallet download.
The rest of my post is about making the wallet act as a decentralised seed for downloading the client. Or at least every (or some) wallets act as torrent seed on on I2PSnark - (http://www.ghacks.net/2007/06/06/anonymous-bittorrent-with-i2psnark/). So the ability to obtain an electrum client is taken away from central servers.
