The limit of 1024 file descriptors is only a default value under
Linux/UNIX, it can changed
by calling

       ulimit -n nr

(nr number of open file descriptors) before starting tinc. I never
tested this with tinc, but with lighttpd it works perfect.
Running Linux, the number of all open file descriptors
is limited by /proc/sys/fs/file-max, but even this variable is writable.

Windows has a higher default value of open file descriptors.
