Jimmie -- my rudimentary setup (Dragon 15 on the mobile laptop, connected to "server" machine at the office thru remote desktop to AC) works extremely well if I have WiFi with a solid 5mbs/sec down and 1 up. That can be with the local hotel wifi, a hot spot on my cell phone or the Sierra card in the laptop hooked to the cell phone tower. It can also be via wired internet -- there are still many places where ethernet connections are available, but no wifi
The key is a good WiFi connection -- and at least out here in the west, that is far from given. Vast stretches out here have no cell service at all, and even in the middle of Los Angeles there are times and places where wifi is subpar (<1Mbs down and <0.5MBs up). Hotel Wifi gets overwhelmed after about 6:30 am, probably with other guests streaming video.
The US has some ways to go before we can say we have adequate high speed internet.
