i see many possible solutions.

1 just insist on seperate files

2 add n special info packets before the actual one containing the font
  each pointing to another subtitle stream and a
  "ContentInNextPacket" entry

3 like above but put these packets after the one with the content

1 is inconvenient for some types of attachments (like cd covers ...)
also it doesnt solve the O(n*m) issue. Of cours solving the O(n) issue
does mean less redundancy, but then loosing the cd cover or even the
fonts is better than loosing the main headers ...
