FPGA solutions for hashcat

[Morris]

I previously modified the bitcoin miner (cpuminer-opt) to send mining jobs to FPGA for mining via UDP. The actual application is at the following URL.

I am considering rebuilding this process in hashcat for FPGA password cracking.
What I want to ask is, is there a demand for this kind of application? Is it worth investing my time in doing it?
