I noticed that as well. Check out this pcap file. I'm calling PingResult
this time and you can actually see the data being returned. PingResult takes
a value and returns it as a the return code. I'm passing in 0x12345678. I'm
trying to take it one step at a time and just trying to get the return code
and error code to be valid before I worry about reading the output_size and
output_buffer. I've got that working. You're right, its pretty much
exactly the same as the old invoke.
I'll implement the reading of output_size and buffer today and send a
patch. I'm not going to look into stream mode at this time, but may in the
future.
Thanks for all the help!

I'm not encountering this problem. I'm guessing its because I disabled all
security in Visual Studio for the device.
