Using Soundtouch units with LMS - just an idea

[pointy56]

We use several Squeeze devices to provide music around the house, supported by a central LMS server which hosts our extensive music library (LMS was previously known as Squeezebox Server). Our Bose Wave Soundtouch units can also be used as LMS players via uPNP.
Our main use for the Bose units is to stream internet radio - when Bose turned off their servers the way that I was initially getting access to our preset favourites on the Bose units was by triggering the stream to play directly from LMS. Having installed Aftertouch on a local server the presets are working again.
But this got me thinking: What if I could send an HTTP request for a preset directly from the Bose to LMS - then I wouldn't need Aftertouch running just to play an internet radio station. I should explain that all of our favourite radio stations are already set-up on LMS to be played via the various Squeeze players, and do this without needing to access TuneIn - also, LMS has a well-defined mechanism for adding new 'plugin' features, including support for supplementary HTTP handling.
I have already prototyped a simple plugin that catches a particular HTTP request and triggers the associated favourite to play on the requesting player. The current format of the HTTP request is very simple: http://:9000?=

So my question is this: Can a Soundtouch unit be configured to emit this sort of HTTP request directly, without needing to access an external server? I suspect that something like the Soundploy v1 solution might work, but it's not clear to me how to do this.

Thanks in advance for any assistance with this.
