Thanks for posting the docs. You are right.. .a host has
max_check_attempts... but NOT while getting a passive host check result.
Receiving this will immediatelly result in a hard state.

Another workaround might be using host eventhandler to only use
send_nsca when the state of the distributed server is HARD.

In my opinion, this work might be a nut.
Ethan's works hardly on Nagios3, don't know how far he is, but I think
it will be released within the next few months or so.
Nagios3 has many changes, good changes and cause of the new host check
logic your hack attempts to get passive host checks working like you
would will die on Nagios 3.
Just my 2 Cents.

Well, I think I don't get this right.
Your remote hosts are not reachable by your master? So active checks
will never be an option?
Why don't you go the way described in:

http://nagios.sourceforge.net/docs/2_0/distributed.html (nearly at the
end of the page)

This would get you an alerting when the passive checks are stale,
instead of doing a normal active check of your services when they are
stale.
