Is it possible to use PHX to send packets to a SPECIFIC client ? e.g. my char's name is iSpoil and the other one is iPwn. I can send a packet from iSpoil directly to iPwn?

sendtoserverex/sendtoclientex

Second, is PHX prepared to automatically get info from one packet and use it on another forged one? e.g. retrieving the objectid from InventoryUpdate and use it in another packet.

automaticaly? what you mean?
there no buildin parsers. you must 'read' objid from packet. remember it and only then use it.
for example : peace of the code from this topick
will remember current character position

var
MyX, MyY, MyZ : integer;
begin
if (ConnectName = 'MyCharName') and FromClient then
   case pck[1] of
    #$48: begin //ValidatePosition:d(X)d(Y)d(Z)d(Heading)d(Data)
           MyX:= ReadD(2); //read d(4 bytes). offset 2. (offsets: 1-packettype=pck[1], 2 - x, 6 - y, 10 - z, look on comment below)
           MyY:= ReadD(6);
           MyZ:= ReadD(10);
          end;
   end;
end.
