Hi Thomas - would not disagree about supporting a 'Linked Data'
approach.
Our focus has been at a somewhat higher level on a potential SKOS
programmatic interface that might facilitate the development of SKOS
based applications and user interfaces - we'd be delighted to see a
RESTful version of any SKOS API.

This surely is a valuable contribution.
However - I wonder if the 2004 SOAP API of SKOS is well aligned with 
current SemWeb.

Shouldn't it be RESTful to fit into e.g. LinkingOpenData?

See "How to publish Linked Data on the Web"

(which supports a SOAP API as well, and not even SKOS, but we'll be 
working on this)
