Less-invasive insulin delivery options

My daughter was using inhalable insulin - Exubera with some success. Now that it has been pulled from the market we are trying to transition back to injecting which isn't going too well. Does anyone have any ideas or experience with less-invasive insulin delivery options - like a patch. Or does anyone know if something like that is in development?

Aside from that setback, things are going well. My daughter seems to be adjusting to her person with diabetes status fairly well. She's starting to let others besides close friends and family know about her condition. She has also expressed interest in volunteering at a diabetes group for kids.
