In this case I would think that for some business users, having their models potentially exposed to 3rd parties would be a bigger issue than not being compliant, for others they may not be able to use Tiertime printers in producing parts on behalf of their customers.
I understand why there is no response from Tiertime, but would certainly be interesting to see if there are users who actually have an issue with this.
@owensparksdid you say in a different thread way back when that you received some information from Tiertime about what needed to be open in a firewall to make UP Studio work at the time, or was that someone else? Currently it seems like once installed and activated UpStudio and the printer will work completely isolated, so there is always the option of doing that, for now.
