Yup, I would like something like that as well.

I hope he will chime in and says how the things are going. In the last
concurrency post on the forum he said that the concurrency should be
ready this or next month.

It was related to blocking operations like readln stopping the event
loop. See
http://news.rejectedsoftware.com/groups/rejectedsoftware.vibed/thread/693/.
No real solution was found as this requires either the fiber support in
std.concurrency or std.concurrency support in vibe.d.
