If you telnet or nc into your rpi on port 3200, you should get a connection and you should get a bunch of garbage. If not, ser2net isn’t working. Is it running? sudo /etc/init.d/ser2net restart (did you do that after changing the config file?)
If ser2net is working then it must be something about the LH params that’s incorrect. Do you have the correct IP address and port? Is there anything between the two - firewalls or routers or the like?

>>> How about a simpler question. I see in the documentation that LH can use a network connection to remotely read. Can a server for that protocol be made for the RPi? That would be super awesome deluxe for me, and assuming it's just a serial-to-TCP protocol should be nearly trivial to write (heck, netcat might already just do it).

Basically, if you have to ask the question, your are probably not ready to attempt the task.
