        As it happens, I did not see that particular behaviour 
during the ~4 years I was at a large cable modem ISP. Perhaps
many employers don't permit folks to directly mount filesystems 
via the global Internet and many employers don't (even today) 
have IPsec/PPTP VPNs as supported items.

        Fully agree about that.  The low-latency, moderate-bandwidth,
continuous media apps really did start appearing significantly 
about 6 months after a market was deployed.
