You assert that there are devices with insufficient resources to run DNS-SD/mDNS.

You assert that these devices would have sufficient resources to run your alternative.

I think you need data to substantiate these claims. Note that devices like the SitePlayer Telnet implement DNS-SD/mDNS in under one kilobyte (about 850 bytes of code, if I remember correctly): <http://netmedia.com/siteplayer/telnet/>

So you need to demonstrate that:

1. That there are devices where 850 bytes of code is too much.

2. That these devices can implement your thing in under 850 bytes.

3. That your thing is useful. I’m still unclear on what your thing is useful for. Your proposal says how devices pick host names, but not how users find out what those host names are, or find out what those devices do, or what protocol to use to communicate with them, and how clients resolve those host names to addresses.
