We're pretty close to being able to duplicate the bitcoin GUI using the RPC. @p{par}

I think the only thing missing is reporting bitcoin addresses in listtransactions.  That gets a little sticky with multisends (one transactions that sends coins to multiple recipients); here's what I'm thinking of implementing after doing some brainstorming with theymos/jgarzik/nanotube in IRC chat and running a couple of 'multisend' tests on the test network: @p{par}


Code:
"category" : "receive", @p{brk}
"amount" : amount, @p{brk}
"address" : "bitcoinaddress"
... plus the rest of what is reported now @p{brk}
(account/txid/confirmations/time/comment).  That's the "received on" @p{brk}
address, of course. @p{par}

On the send side, I'm leaning towards: @p{brk}

Code:
"category" : "send", @p{brk}
"amount" : amount, @p{brk}
"fee" : fee, @p{brk}
"toaddress" : { "address" : amount }  #  or "toaddress" : { "address" : amount, "address" : amount } for a multisend.
... plus the rest of what is reported now @p{brk}
(account/txid/confirmations/time/comment). @p{par}

I don't like that the common case looks kind of ugly; I'd much prefer @p{brk}
just 
Code:
"address" : "bitcoinaddress"
 @p{brk}
That could be done by having listtransactions report multiple category:send entries for a multisend... except it is not obvious @p{brk}
which one should report the fee, if there is a fee.  First one?  All of them? @p{par}

I'm also a worried that websites might get their accounting wrong if they're not prepared to deal with multisends; making "toaddress" an @p{brk}
Object makes it obvious that multisends are possible.  The only way a website would get a multisend would be if they allow users to import keys from their local bitcoin wallet, which nobody is doing... yet. @p{par}

 @p{brk}
Here's how listtransactions currently reports a complex multisend: @p{par}


Code:
   { @p{brk}
       "account" : "Test3", @p{brk}
       "category" : "receive", @p{brk}
       "amount" : 3.03000000, @p{brk}
       "confirmations" : 66, @p{brk}
       "txid" : @p{brk}
"36c86ca499275945a3f1805d6e070ac00b2d32e5e16a4c9cf2c83b189a347d88", @p{brk}
       "time" : 1292532062, @p{brk}
       "comment" : "multisend, Test1 to Test2 and Test3 twice (same addr)" @p{brk}
   }, @p{brk}
   { @p{brk}
       "account" : "Test3", @p{brk}
       "category" : "receive", @p{brk}
       "amount" : 3.00000000, @p{brk}

   { @p{brk}
