rednet with arguments over send/receive

I have 2 servers setup and i was trying to get the client to send a message with arguments to the server in which could use those arguments in code. I couldnt figure out how to so i just have the client send additional messages to act as arguments. Is there any way to just send additional arguments over one rednet.send()? Or is this impossible?

You can send a serialized table, and unserialize it when it's received. See http://computercraft.info/wiki/Textutils_(API)
