teamviewer is free for personal use
I think this would be charting a bit of a grey area, as technically it would be for business use as one would be using it to access software for a business related endeavor and if continuing to use it as such it would be related to a business type of workflow.
Just a little bit of a grey area in my mind.
If you have a subscription you can have it installed on two computers at once. To use either one, you'll have to use license manager to remove the license from one machine and then the same to activate it on the other one. Internet connection req'd on both. Not a great method though but it works.
This is about the only way to do it, unless Flexi allows for a network license, either via dongle or thru subscription. I have one software that allowed that via dongle. Expensive as all get out just for a single
computer use license. One license for one
computer is double the Flexi's perpetual license, so I can only imagine what their network license options would have been like.
