not before 2.0. yours is the first request for this feature that i have seen in over a year, so it's not like a lot of people are clamoring for this. i believe that the majority of people who use XBMC's advanced media functions like the library/database stuff already know how to do something as basic as getting their tags sorted out. a lot of people (including myself) use Tag & Rename to do this in an automated fashion. it makes tagging just about as painless as can be, AND it can embed album art into files.
http://www.softpointer.com/tr.htmthe one they have for download is a "trial" version and is only limited in that it nags at you when you first open it up and it will stop working after a month, but it should suffice for your tagging needs of the moment...
