I would love to read more about that. Where can I find a
good reference?

I will think about it. There is the B.F. CHELLAS 1980 book
introducing modal logic which is very good as a textbook without
much motivations.
The new edition of Hugues and Creswell is simpler and provides
more explanation. Van Benthem's guide on "intensional logics"
gives more "philosophical" motivation, but not so much proof.
Boolos 79 is rather good for modal logic, but only with the Godelian
motivation. Mmmmh...

Well, that's just where I guess we come to disagree... :)
I am still not sure I believe comp,

Good!   Comp is really unbelievable, especially by sound machines ...
(of course this should be nuanced especially because here
"believe" is very informal). But nobody should believe that I believe
in comp, I believe that comp is fascinating, no more. Well if my work
is correct then we can also believe that comp is refutable.

so I am not
yet sure I agree that the hardware doesn't matter at all...
Or at least not in that strong sense that one can
expect to experience a copy of oneself elsewhere.
I am not even sure what 'one' means here...
So many doubts... :)

Just in case you find the time, it could help me to better understand
your position if you tell me where in the UDA reasoning you would
disagree: for example in the conversation with Joel Dobrzelewski:

UDA step 1
UDA step 2-6
UDA step 7 8
UDA step 9 10
UDA last question
Joel 1-2-3
Re: UDA...
Joel's nagging question

I say this because an _expression_ like "the hardware matters" is rather
ambiguous .... It could help you to understand why you don't believe in comp :)
Or why you have many doubts. With comp doubts can only grow ...
