Glad I could help add some color to the discussion.

I don't see the issue as overly complex.  Things like C2N232 and an 
IEC->USB or IEC->Ethernet solution can simply run a small app on the 
machine that checks for a file or something on the PC side.  If the file 
shows up, dload it and run.  Or, the file could be a marker file, which 
includes a start address and the name of a file to load and sys.  There 
are a number of variations on the theme, and I think most cross dev 
solutions employ something like that.

I will say, along Marko's comment, LPT and COM ports are gone from most 
machines.  I doubt you'll find much contemporary development tooling 
that uses those older methods.  However, if you do have an older 
machine, 64HDD should fit your goals.  Run 64HDD on an old PC with LAN 
network drivers.  Set up 64HDD to use a LAN share, and Cross dev to that 
share from another, Windows/Linux machine.
