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
