I think this is a good idea so it can work with DVB simulcrypt 
EMM/ECM, right?

We also have an application for private streams (video associated text
metadata) 
to multiplex into mpeg2ts.
we tried using the ffmpeg dvb subtitle options 
-i myfile.txt -sbsf text2movsub -scodec copy
but it is too restrictive and there
doesn't seem to be a way to just use a general bytestream source 
for input (as noted in thread by Giuliano Uboldi Jan 14 2009)

So we are thinking to use this patch to multiplex the private metadata.  But
I'm not sure if this includes the encode patch, or only the decode
patch to receive private streams?

Can you tell us how the encode was done?  is it with a new command line
option or API?
