After considering all the options, I think I might just get this! My only query is, I'm on Windows XP... will the software work? I got FPP to work, by downloading the "giveio" driver.. but FPP is a windows application which uses API calls to activate the driver. AFAIK DOS programs (wisp.exe) can't do that! There's a comment says "will work on NT-based systems with correct driver".. What driver would work?
