The nice thing about DRb is it's all pure ruby. Digging about a bit:

    def main_loop
      Thread.start(@protocol.accept) do |client|
        @grp.add Thread.current
        Thread.current['DRb'] = { 'client' => client ,
                                  'server' => self }

So in your method handler, try looking at 
Thread.current['DRb']['client']. I think that will be a DRbTCPSocket 
object with a peeraddr method.

Simple demo (client and server in the same code):

require "drb"
class Foo
  def doit
    return "You are #{Thread.current['DRb']['client'].peeraddr.inspect}"
  end
end

DRb.start_service("druby://0.0.0.0:9999", Foo.new)

o = DRbObject.new_with_uri("druby://127.0.0.1:9999")
puts o.doit
