Huh? Do you understand how Sling, or LocationFree for that matter, works?
If the PC/Mac SlingPlayer goes with the LocationFree or SlingMobile model, you will need a unique serial key on each device's installation of the player software.
Knowing the way Dish nickels and dimes their customers, I'd say it's a very real posibility this will be happening with the player software.
You missed my point.
They provide software with the device, at this time it has unlimited licenses (for installs) for PC and MAC (but Mobile costs and wasn't even available when I bought my Slingbox).
It's probably likely they'd provide ONE license with the device (even if they went the total licensing method instead of PC/MAC being free and other options (Like the mobile client) costing more).
I can't watch the Slingbox from multiple machines at the same time, because my device can only serve ONE connection. I don't really see the issue with requiring the purchase of additional player licenses because it wouldn't affect me in the least (I always watch from the SAME single device, my field laptop).
If someone REALLY needed Slingplayer available on several different devices to play that ONE concurrent stream, I suspect they would feel a lot different than me. I'd be interested in the numbers, since the people I know with Slingboxes are usually in my boat of having 1 device to play from.
Either way, they can't suddenly decide tomorrow to start charging for the Mac or PC client. You could stay using the SAME VERSION you're using now, forever and ever. Sling doesn't owe you any upgrades, doesn't owe you any additional OS support for free. But, the device will still work as it does today, for quite some time into the future (until it's outmoded, until your OS is outmoded, until lightning strike, etc.).
I don't think I can make this any clearer. People who have the device and use the device today LOSE NOTHING, they may never GAIN ANYTHING (features, etc), but they LOSE NOTHING.
