RE: [dsdp-tcf-dev] Applicability of TCF agent for remote tracing

Yes, binary data will go through but will be copied/encoded. This is not
acceptable when tracing a busy high performance embedded server (e.g. a
telecom server). If it is a small device, with only a 7 bits RS232
connection, falling back to this less efficient default mode would be
appropriate.

Yes, we should probably extend Channels, Streams and JSON to have the
option of zero copy block writes whenever practical (e.g. TCP
available). Michael Sills-Lavoie is working on that and will likely post
a proposal (.h files) for comments. Thanks.
