Mashup FAQ - Frequently Asked Questions - Presto APIs

Can you only pull live data in via XLS files, or from SOA, JDBC, API, etc. and if you can, how?
JSR-168 is nice, but it doesn't help me as an ASP.NET developer. Is there support for displaying mashlets in ASP.NET apps?
Is there an example of the Presto/Silverlight API binding that you can point me to?
I guess the Silverlight question is really: do you have an API that allows me to do that binding? Or do I need to do it myself at this point?
What is the deliverable to the client? A mashup? Mashlet? I'm trying to understand how the application dev process changes in a mashup architecture.
Is a Visual Studio plugin also available?
What kind of things NEED to be done via API instead of visually?
How the Mashups are being handled for different devices display capacity (PC, iPhone, Blackberries, etc)?
Can widgets only be viewed on web browsers or is there support for programmatically accessing widget data from .NET or Java?
In the examples on competitive analysis, were APIs used to get data from different sources or was data obtained via HTTP and then parsed? I'm guessing a lot of retail sites don't necessarily provide APIs to access their price data.
Regarding ‘api enabler’...are you using the browser source or more of a screen scrap for creating an external website API?
How do we deal with lack of service level agreements for APIs from external sources? What are the workarounds?
What about how reliable an external resource can be if it's not under your control? What if Google suddenly changes their api or interface or eliminates it?
How does this compare in construct and operation to the Portal/Portlet style of web page composition.
Are the Presto services exposed to other systems such as OpenESB?
Do you have connectors to sources such as OLAP cubes?
How much does the use of mashups increase storage need and capacity? It is obviously inherently dependent on how many... and how long they hang around or are for re-use... but is the impact huge?
Can you only pull live data in via XLS files, or from SOA, JDBC, API, etc. and if you can, how?
Can anyone share a mashup using the Salesforce.com API?
