Is a og xbox vmu possible?

[Daydreamer]

Just seems like if the ps1 has a aftermarket memory reader and the dreamcast has a vmu, then everything after probably is capable of having something similar. Doesn't make any sense that they didn't make any for the xbox or the 360 even though it has a harddrive, being able to delete and play games on the card externally without plugging up xbox seems like a pretty good idea.
