You can add an existing project from anywhere (at least in Windows Forms, I don't know if it would be any different with an ASP.NET project). Just right-click on your solution and choose Add | Existing Project and then go find it. It should work (I haven't done this "for real" ... but it worked in my test solution, so no guarantee <g>).

What we've done in similar situations is to use Source Control and have only one copy of the project (and it's files) on Source Control, but share it among different Solutions (so, yeah, we'd have multiple copies on your local drive, but only one copy in Source Control).
