AF Table Link via Web REST Query or SharePoint List
Having the ability to query cloud-based data, web data, or SharePoint data would further leverage the ability to bring in various data sources.
Having the ability to do a web call would allow us to connect to so many more data sources. Sharepoint Connection would also help a bunch. Since many Document systems are either web-based or Sharepoint Based this opens a whole other world.

A SOAP web service endpoint would also be a great addition if this feature were to be implemented. Either a new Data Reference or a Linked Table option would work.
