Jeff, the upcoming SPIN 1.1 and TBC 3.2 releases include SPARQL UPDATE support in SPIN. The SPIN RDF syntax will support it, and you can define properties that have sp:Update as their range to store them as part of a model.
I have plans to also allow INSERT and DELETE in spin:rules, but not for this release. UPDATE queries are also not allowed in SPIN functions, but can be wrapped into SPIN templates. If you have different requirements please clarify.
