That was badly phrased, I'm sorry. I meant rather generic playback apps.
If it's just stuff being playbacked there's ofcourse no problem using
gst directly, although it's, i would think, inconvient. When the code
duplication and possible inconsistencies for the user creep in it's
starting to become serious. This is the case with player apps that also
access CD devices and stuff, since you want f.e. settings for them to be
shared.

Well, that's probably right. Although there is already a lot of code in
monkeymedia that could be reused for metadata, inet radio, audio cd
(which is in the make), etc.

Well, it's something we need to get sometime imho (as you all well know
by now.. gah). There don't seem to be many enthusiastic reactions here
though so I'm not going to take this any further.

Well, this was meant to be a start of a brainstorm for _possible_
features for the API, so no surprise these things look like rb since
they are things i bumped into - when writing rb.
