I would like to see a project that allows users to create a file from their designs/drawing/map and take that file with it's embedded data out to a field site on a mobile device. Check the objects and its embedded data, if needs to be edited then a way to make the edit then when they get back into the office have it update the design/dwg it came from. Not the dwf markups that we have now. Some thing so if I take a Map3D dwg with either object data or FDO data out to verify in the filed, I see that a utility pole data has 50' as the height but it's real height is 45' to be able to change the data on the spot, then when I get back in the office click a few buttons and that edits are made with very little users intervention. This should also work with REVIT so that a user can update as builds from the field, if a door element is listed as Steel 1 hr fire rated but in the field it is a wood door with no fire rating the user can make the changes on the mobile device then update the as-builds back in the office with one/two button clicks. Now the platform for it to run on needs to be something that runs on the I-Pad, Windows Mobile, Tablet PC and such, we don't need to carry around a $3000 laptop in the woods or construction site.
Personnally I like the Window Moblie platform so it can be installed on handheld GPS units that many of the Map users already have. : )
