900 MHz radios are widely used in the electrical industry. As a matter of fact, most of our radio controlled devices out in the field use 900 MHz frequencies to operate. In a big city, there may be a 900 repeater at the top of a large building (say for instance the Westin Building) that would be sending out signals at fairly high power. It would be very easy to cause intermod with a robot signal which isn't even close in terms of power to a repeater. You would need some sort of PL or similar encoding to prevent massive issues, but you would still be at a high risk for intermod.
I think what it comes down to is...radio frequencies are everywhere, we might just have to live with the nuances of interference for a while.
Dave, do you remember when RNETS would cause for many rematches in FIRST as a result of the radio being on the same frequencies as Orlando International Airport? God I miss the old days.
