Yes, I think it would be possible to do this. (The most difficult part of this
would be to modify the application that generates the index file (not 'hint
file') for each transport stream so that it doesn't halt when it reaches the
end of the input stream, but instead (somehow) continues, after waiting for
more data to be arrive.)
This couldn't work, however, if you had a file 'buffer' that didn't grow
indefinitely, but instead 'chopped off' old data from the start of the file (so
that the file maintained a bounded size, rather than growing indefinitely). If
that's what you want to do, then the index file mechanism probably could not be
modified to accommodate this. Instead, you would probably need a different
implementation of 'trick play'.

Yes, I ("Live Networks, Inc.") am available for hire to develop custom upgrades
to the source code. If you're interested, please let me know (by private
email).
