I'll take a look at what Hound could do for Saera when I get an invite for the API (it's invite-only at the moment).

Progress update: Sailfish OS port is just about ready for release, once I figure out packaging details.
I've been working on the Harmattan port, as well. Here's what I've found:

• The old version of PyOtherSide that works with Harmattan is synchronous, meaning the UI hangs while commands run. Hopefully I can work around this with threads or something.
• Harmattan makes it much more difficult to do things like set alarms or read contact lists than either Maemo or Sailfish OS - it looks like I may need C shims for some functions.
• Harmattan uses a different name for ld.so (the system linker) than Maemo or Sailfish, meaning all the Julius binaries needed to be recompiled (despite it being the same CPU architecture - odd.)

So Harmattan port will not be released just yet, but hopefully will be fully functional by the end of the summer.
