Not exactly streaming, but I did something like in dsas.
I'm sending function as string to server to execute.

There is this code in tests.lua:

function test_testapp_test3(S)
     print("------- send function to execute (danger!) ------")

     local ss = [[
         -- from PIL p:33
         function maximum(a)
             local mi = 1     -- maximum index
             local m  = a[mi] -- maximum value
             for i,val in ipairs(a) do
                 if val > m then
                     mi = i
                     m  = val
                 end
             end
             return m, mi
         end

         return maximum({8,10,23,12,5})
     ]]

     S:push(ss)

     local rc = S:call("testapp", "test3")
     errreport(S, rc)

     local m  = S:result(0)
     local mi = S:result(1)
     print("m:" .. m .. " mi:" .. mi)

     print("passed...")
end

You can get dsas from http://www.dynaset.org/dogusanh
