Would a simple diff between 2 pg_dumps work if only data is being added in the
database (i.e. no alters or tables are added)? So say I do a pg_dump once a day
and one every 3 hrs there after and in the script I do a diff and store as a
PITR dump. Will that work, or is it too simplistic?

If you are going over an ssh connection then scp seems like the appropriate
tool. Yeah, rsync would work, but it's just a useless extra layer of
software...
