Ok.

Suggestion:

should not we make it possible to detect this?
Meaning the virtual support for ftpd. for example, will 
call getsockname () and base on the IP/DNS choose the virtual domain
for the user.
Within the current code you add, it should be possible to add this,
although I do not think you'll have enough time in your schedule
to squeeze this one in too 8-)
