Security is the big problem, even if not international. You essentially have to connect computers with trade secrets (source code, CAD files, etc.) to the internet, which is a big no-no.

If you go international, then you are probably dealing with a legal system that is stacked against you. The government probably even intends to divert your trade secrets to fully domestic (relative to them) companies, and will apply pressure to "your" employees (who may even be government agents) to make it so.
