Requesting [wanted-1.9].

What timeline are we looking for? Beta? Or can this be done post-beta.

And just to be clear, this is not a UI bug, it's for implementing getting the list of applications able to handle a specified mime type?

Colin - yes, mime-type or file extension, whichever mac works with. This is similar to Finder's "open with" context menu.

Also note, bug 400852 - we'll be adding protocol app picker support at some point.

I'll look into at least the API to use. This *is* on my radar.

Alright, so I looked at what you'd need to write this morning. Here's roughly what it would look like (memory management ignored):

CFStringRef uti = UTTypeCreatePreferredIdentifierForTag(kUTTagClassMIMEType, someMimeType, CFSTR("public.data") /* hint since we're looking for files here */);
CFArrayRef handlers = LSCopyAllRoleHandlersForContentType(uti, kLSRolesAll /* might want to be more restrictive? */)

and then convert that to whatever array type we need. Documentation at these two links:

Re-requesting blocking-1.9+, as it turns out this blocks bug 404434, and that already has blocking-1.9+.
