Hmm, now that's a good question. I have looked into remotely
programmable options, but have always settled on either logging into a
PC remotely connected to the board through a JTAG cable, or using a
systemace type solution (the projects I work on are prototype project
with very low volumes).

SystemAce is an asic from Xilinx which allows you to program an FPGA
from a flash card. It has an MCU port on it that I believe allows you to
reprogram the card through an MCU (never needed this functionality so I
haven't tried it), so that is an option.

Otherwise unfortunately I don't know of any other solutions.

Thanks, TTYL
