Even back in the 90s, I knew people who would bring a separate travel laptop that would just have the basic set of apps and a VPN client. So, once you got to your destination, you'd login via VPN and download what you needed. This was at Nortel, so it's not like it was a very high security company, just moderately secure. Not everybody did that, but certainly enough people did. The department kept a couple spare laptops for just this purpose that would get wiped and restored to their default config after the travel.
