As sharepoint 2010 can not deploy back to the source what could be the best method of getting data back into the source site collection?
eg lets say a webpart asks a user some questions, which needs to be added to a list. The question is how does it get into the Source site collection copy of the list.
Currently the only method i can think of is the webpart calls a WCF service which does have permissions through firewalls back to soure site collection, where it updates the list.
Any other or better suggestions?
