There are not really time constraints. For Ubuntu Precise 12.04 cups-filters 1.0.5 with texttopdf being fully fontconfig-based is enough. Precise comes with suitable TTF fonts. Currently, the change is more thought for upstream to be prepared for the first distros which drop TTF fonts.
Ok. I've looked a bit more into it now; the metrics are actually available in the usual form (hmtx-table). The only issue seems to be whether to only support PDF 1.6 (native OTF-CFF support), or also earlier versions, starting with PDF 1.2, which requires extraction of the CFF chunk (haven't looked at the details yet). Actually we currently claim PDF 1.3, but I'm not so sure, that I don't already use PDF1.6. features (libfontembed is called with EMB_DEST_PDF16 ...).

I think that at least basic (non-subsetting) CFF support can/should be available and is easy enough to provide. At least PDF >=1.6 support seems achievable in a reasonably short timeframe.
Everything else can be added when there is an actual need.

PS: The term "SFNT-flavoured OTF" in my previous message is rubbish; what I meant was "glyf-flavoured".
