I'm testing a new HP Thin Client t520 and decided to see how it would handle OpenVPN and also SmartSDR 1.8.3 from the office figuring if it works well maybe use one dedicated to the radio at home.
After installing and configuring everything it worked like a charm! I don't know how it would work with a Flex 6700 but using 2 slices from my 6300 worked great!
$395.00 for the thin client new is a bit much but they can be found on eBay cheaper. I'm going to use one from the office during lunch to see how it works over time.
