It is better than rewriting later if a lot of things change. It's still in a very early state (barely enough to run a TCP based server) and the user facing API will stay more or less backwards compatible. The main exceptions are that some callbacks will now have to be nothrow and/or @safe and that some types change from class to struct. So at this point I'd not recommend this for anything more than quick experiments and possibly as the basis for early feedback about certain API decisions: https://github.com/vibe-d/

This is great news. Will the new HTTP package support an endpoint address and transport abstraction so it can be used over Unix Domain sockets, Named/Annonymous pipes and other stream types? I have looked into implementing Unix Domain sockets support for vibe.d(more specifically the reverse proxy module) and noticed that enabling HTTP over UDS would be a fairly big and complicated change. Working on it is still on my todo list but if the the abstraction is going to change anyway I might wait until it has settled a bit. I am also willing to look and help with the abstractions before they are included in an official release if it would not interfere too much with your work. It would be pretty straight forward to add a low-level HTTP protocol layer that works on an existing ConnectionStream. I'll keep that in mind.

One of the big issues for the project I'm working on is that the current implementation is not @nogc and nothrow (while most of my code that doesn't interact with vibe.d is nothrow, @nogc and where possible pure). Another thing that I would like to request is support for std.experimental.allocator. I need to be able to provide an allocator through which all vibe-core allocations should happen. Just to clarify, I'm only interested in having a @nogc/nothrow event loop, as my project is a rather low-level (it is meant to be used both from C and D code) and I won't need the other parts of the framework (like web, db, etc.). And I think it's OK to use the GC for application-level logic. Everything is @safe and nothrow as far as possible. The plan is also to basically have no dynamic memory allocations after the warmup phase. However, @nogc is still difficult, because still a lot of Phobos and Druntime are not annotated, and because that would mean that all callbacks would have to be @nogc, too. Especially the latter can only be solved by converting the API to take callbacks as an alias template parameter, but if possible I'd like to keep the possibility of passing an `interface` around to hide the implementation...

Would that library support the same event sources as libasync ie. filesystem, notification, sockets etc? Yes, it would be sockets, files, file/directory change watchers, timers, manual events, posix signals and DNS lookups. I really think this kind of thing is missing in phobos atm. no matter if it is a new lib from you or libasync+optimizations.
