As a TIVO owner I have learned that several persons/companies offer hacks/upgrades that include all labor for folks who are afraid of doing such themselves(For TIVO some changes require HW upgrades too). Perhaps someone might be interested in providing such a service to include LABOR for adding/changing font(s), fixing the battery bug and other COMING applications that use the universal flasher.
In the absence of such a service, if someone writes a Windows application that holds the user's hand and has lots of error checking,help and de-bricking options included for those of us who are "procedures challenged",
even the most timid among us could use the likely many new appls using the universal flasher. "Shareware" perhaps?
