    Paper
In summary, the conversation discusses the topic of propagation of light in Doubly Special Relativity (DSR) and the various theories and variants that exist. It is mentioned that DSR is not yet quantized and happens in flat space, but there is a need for it to blend into some quantized model. There is also discussion about the possible smoothing out of Planck scale singularities during quantization. The speaker expresses a preference for the Kowalski-Glikman brand of DSR over others, but ultimately, the choices are not up to them. The conversation concludes with the mention of a paper on the subject.

Things become infinite near the Planck scale. Killer?

BTW notice that their theory is not yet quantized.

There are a lot of variants of DSR (as you know!) and they
predict different things, but two features they all have in
common is they are not quantum theories
and they happen in flat space.
The bridge to General Relativity and then on to
Loop Gravity (quantized version of it) has not been
constructed yet.

I think it is about time for DSR to put out a feeler into curved space, and blend into some quantized model.

I don't know what Planck scale singularities could be
smoothed out during quantization.

If I had to choose with incomplete information I would
pick Kowalski-Glikman brand DSR over Magueijo brand. And
KimKimRimYee brand might not even get carefully considered.
But I am not making the choices! So I was glad to see their paper.
