Is there an advantage to using mashups vs. iframes in SharePoint? Are mashups more stable when rendering visualizations? One limitation I've found, not sure if it applies to mashups also:
For SharePoint iframes, I've found embedding multiple iframes on a single page is prone to latency and parallel session errors. Instead, I'm relegated to embedding an entire sheet as an iframe. Would mashups run into a similar issue? Are there any other benefits to using mashups over SharePoint iframes?
