I can't really give any advice on how you would do the networking part. I know some users have used WCF, and others use plain http calls. You might investigate some of the add-ins built on top of Excel-DNA - e.g. FinAnSu and Cubicle Tools - they might give you some ideas. There are links on the CodePlex home page.

Good luck,
