Two paragraphs below describe ISR briefly.  Attachment is
IEEE Computer article with more details.

Internet Suspend/Resume (ISR)

The term "mobile computing" typically evokes images of a laptop,
handheld, or wearable computer.  However, the plummeting cost of
hardware suggests that pervasive computing infrastructure could
minimize the need to carry such devices in the near future. In
such a world, personal computing will be available anywhere on
demand, like light at the flip of a switch. Only when a user
starts to use a computer will it acquire his unique customization
and state. When he finishes using the computer, this
customization and state will disappear from it. Thus, a user
could travel hands-free yet be confident of making productive use
of slivers of free time anywhere.

This is not just a dream today.  Internet Suspend/Resume (ISR) is
a pervasive computing technology that rapidly personalizes and
depersonalizes anonymous hardware for transient use.  As its name
implies, ISR mimics the closing and opening of a laptop. A user
can suspend work on an ISR machine at one location, travel to
another location, and resume work there on any other ISR machine.
Hardware virtualization and file caching are the keys to ISR's
precise customization and simple administration.  Our approach
eliminates the need for modifications to guest applications or
guest operating systems.  In particular, ISR supports unmodified
Microsoft software including any of the Windows operating systems
and the Office application suite.
