completely missed the sendtoalias command.
Yes, it's working (it as a beta version, may still change, so it is only present in my github tree :
https://github.com/khalahan/namecoin)
would be interesting to also add a sendbtctoalias command that would open a bitcoin uri: bitcoin:1bitcoinaddress
Indeed, it could be a simple way to start managing bitcoin aliases.
Does the main client bitcoin client support uri schemes ?
