This might be more appropriate for the libsl-dev list, not sure. Anyways 
I have never seen a client receive the DenyTrustedCircuit packet before, 
you may be doing something odd like sending the wrong SessionID or 
something like that. To get all the way to receiving Object* packets is 
a long ways, but it looks something like this:

<> XML-RPC Login
-> UseCircuitCode
<- StartPingCheck*
-> PingCheckComplete*
-> CompleteAgentMovement
<- AgentMovementComplete
-> AgentUpdate**
<- RegionHandshake
-> RegionHandshakeReply

* That's not the necessary order of the ping check sequence, it starts 
up as soon as you connect
** You only need to send one of these to unghost and start receiving 
updates from the simulator, even though the official client would be 
sending several per second right now

Try making your program connect through SLProxy to confirm what you are 
sending out is correct. The above sequence doesn't take any CAPS in to 
account but you don't need to connect to a CAPS server if you don't plan 
on moving to a new sim and only want to see object updates.
