It's not critical, but it seems that the IDPF is moving towards standardising "application/vnd.ms-opentype" for both .otf and .ttf files. See http://www.daisy.org/epub/issues/mis...ype-font-files.

No, what they are saying is that they will specify "application/vnd.ms-opentype" for OpenType fonts, which they have done already. See
this part of the OPF 2.0.1 draft. They have left the media type for TrueType fonts unspecified. AFAIK it will remain unspecified indefinitely since they believe that we should all just use OTF fonts and forget about the hundreds of TTF fonts we already have. Fat chance.
"application/x-font-ttf" is the
de facto standard as a TTF MIME. See
this issue on the FlightCrew tracker for a rationale. Even ISO/IEC 29500-1:2006 (OOXML) uses it, and ISO/IEC JTC 1/SC34 recognizes it as the "unofficial" standard.
