Not true. You can code-protect with an LVP progger like yours, and the
LVP/HVP distinctions has nothing to do with prototype versus production
programming.

I think your students will find a way to fry a PIC long before your
erase busget runs out.

To me that sounds like you should use a bootloader instead.

If you do want to include a programmer into your design we could come to
an agreement - this has been done before. But IMHO you should consider a
bootloader.

RJ PCB plugs are a rare breed. ICD2 provides an RJ socket and a two-plug
cable, which is normal for RJ. I don't know if the ICD2 circuit is
available, but the circuit of various Mircochip target boards that use
the RJ plug are available. If you want I can send you the pin
assignment.
