I think I can maintain backwards compatibilty.
I'm planning on putting something in the reply to one of the players inital requests, that I can parse and recognise "hey -new style server" or not. So I can maintain backwards compatibilty with very little code.
Time is the issue. I don't have it right now.

There are two basic strategies here:
1) Create a mixing object, which can handle audio from multiple sources and
generates a single output; hook this output up to the audio driver
2) Do a non-mixing switch, such that audio comes from either one source or
the other; this is closer to what you are describing
The second is far easier. Still, you will have to answer things like "what
do you do if you interject a sound snippet that ends in the middle of a
buffer". If you are just doing beeping noises it's probably a non issue
since you can control the length.
On the alarm clock issue, i actually started working on this, but kinda gave
up. My idea was to do a clock-radio type of setup, where you could select
content to play when the alarm goes off. Unfortunately none of the
content-querying stuff is set up to work like that, and i had a few other
projects that were more interesting at the time.

The content querying stuff is pretty brain dead, and the device doesn't have
a lot of memory; if you query for "artists" the server will send it all
back, and rioplay will choke.
Personally i use[d] a perl package called mserve for serving content. It
should be easy to modify this to support query ranges, such that you do:
And then make new queries from the device for subsequent ranges as the user
steps through the menus, or as they play through a given playlist. Part of
this assumes you can do a query like:
To just get a total number of artists. But this breaks compatibility with
Makes me wish i had more time to work on such things. Best of luck with your
