I would like to negotiate TN3270E mode and stay in it for the duration of the session. Passing NVT data inside TN3270E mode will let me do that. Also, it is explicitly required in the draft and will eliminate confusion about what support is required. We want to be able to alternate from 3270 data streams and NVT data streams, without the arguments we occaisionally get from client vendors.
