I would like that eDrawings and SolidWorks can connect with other SolidWorks or non-SolidWorks users for share file and collaborate with a markup tool and chat.

If you think it is interesting, go to http://www.solidworks.com/sw/communities/2010_topten.htm
In the 'Search Brainstorm' box digit this texts 'Data Sharing and Collaboration' and vote it.

Available for clarification,

Alessandro
