With Motorola having proprietary algos like ADP for p25 and Basic and Advanced Privacy on trbo I don't think everyone will be going AES any time soon. There was a mandate that any radio sold with encryption must now also have AES included as well. So if you buy a radio with ADP it must also have the a software AES option as well.

You can't really call ADP proprietary to Motorola anymore. For the last 5 years (prior to the partnership) both Harris and Tait have offered ADP encryption on their radios (named RC4 after the actual algo). Also, since the 5100, EF Johnson has also supported some form of ADP encryption (granted the 5100 did use XTS3000 UCMs)

Nicely summed up.

and 3) Radios sold with "proprietary" encryption like Motorola ADP will also include AES.

This has essentially boiled down into agencies using federal funds either buying radios with ZERO encryption, or with single-key AES at minimum. Usually going towards the latter since Motorola and the sort would rather do single-key AES (a la APX900) than to reinvent the wheel to pull ADP.

The reason for all this came about that less-informed police chiefs/commissioners were buying radios with ADP only encryption and then saying "well we bought radios that followed CAP recommendations". DHS essentially closed the communication gap between manufacturer and buyer.

I can be somewhat off in my description - but that is how it was broken down to me when this all went down. It didn't personally phase me one bit since we were building out the statewide P25 upgrade to be AES capable anyway.
To add to this, a handful of times a year I deal with federal customers (the three lettered agency kind) and after CAP encryption standards were changed, many have had deadlines set of when they have to be AES256 capable (or running it in place of their existing DES-OFB standards). For some, that means buying new radios as they are running radios that they cannot physically acquire AES256 hardware for and due to long purchasing processes (measured in years) have to plan it out over a several year process.
