Considering that VoiceXML is an industry standard and IMS or IMS-like 
networks seem to be really coming, I have sometimes also thought about that.

If it is about implementing real-world high performance services in 
SEMS, DSM is more powerful and faster. Anyway, in IMS model there 
usually is AS and MRF separated, which makes even simple call flows 
quite complicated.

Implementation-wise I think it should be possible to write a VoiceXML -> 
DSM script converter (maybe even as XSLT), possibly with some DSM helper 
modules, that could possibly be the simplest implementation. It would 
then have to compile and reload the scripts online. For embedded 
scripts, there may be the need to embed some ecma-script interpreter 
engine, but this could probably done in a DSM module.
