I don't believe the "Summon" feature will ever be allowed anywhere, at least for 20 years. Obviously it is too dangerous and unpredictable.
20 years... in the technology age?
Let me give you a sample of technology
20 years ago:
"Intel announces the immediate availability of the 150 MHz (60 MHz bus) and 166 MHz (66 MHz bus) Pentium processors. Pricing is US$547 (150 MHz) and US$749 (166 MHz) each in quantities of 1000. The processor operates on 3.3-volts of power, and utilizes Intel's 0.35 micron BiCMOS manufacturing technology."
"Microsoft releases the
Windows 95 Service Pack 1 operating system update."
"At an emergency meeting of the board of directors of Apple Computer in New York, CEO Michael Spindler is replaced by Gilbert Amelio"
"Iomega ships the one-millionth Zip storage device."
"Western Digital announces the 3.1 GB Caviar AC33100 hard drive, using the Enhanced IDE interface, with 12ms data access time. Volume production is scheduled for June, with a Fall release time and retail price of US$549."
"The USB Implementers Forum approves the USB specification."
So... no. We're not 20 years away.
