"Cunnison puts the total number of handheld IFE units currently in circulation at 12-16,000 from all manufacturers and expects to see this grow 400-500 per cent in the next few years: “We’re targeting a significant share of that market.”

There was a comment by one poster that of the 12-16K units already in service, about half are probably e.Digital related via the past digecor connection and current Mezzo business. 

Should Blakeley be able to continue along this projected growth curve based on current eVU success along with riding the digeplayer history, IFE alone could be self sustaining.  But as you note, eVU opportunities outside of IFE could be an even more significant...hence the point you illustrate.

It's getting more interesting even without the IP protection efforts.

Now to make this investment "significant" !  lol.
