My2c. I don't think Linked Data can be presented as a technical challenge; it is rather one possible solution to a technical challenge, which is the integration and linkage of independent and heterogeneous open data. The comment from Andreas ("I plan to show mostly demos with single-source data (as the majority of currently available apps fall into this category)") seems to raise the issue of using multiple sources into a single application. This means not only data integration, but also reliability of sources, uniform access, fast connections. Another big challenge is data quality. I think we all agree that we cannot expect open data to be published in pedantic RDF (I just attended a talk by Axel Polleres on this topic), but below a threashold it can be too difficult to reuse and mash-up data. Not to mention data freshness, trust, provenance. A third idea could be fine-grained data access and control. It must be possible to represent clear access policies and even machine-readable licences on how data can be used under what conditions. And this in a scenario with many different legal systems. A final (obvious) point, which is of course related to the issues above, is the creation of a shared collection of good practices in publishing open data. This would be very helpful for data administrators and for developers.
