Boot from VHD, anytime?

Of course, the developer is working on it for the final release once Easy leaves beta (We might get it in a future beta build before than).
One thing I will add to this is that if you have a vhd boot entry already there then EasyBCD will currently modify the entry and remove the lines needed to do that boot. It will be reverted to a standard boot entry. This doesn't matter if the windows 7 installer did it (secondary windows 7 install) or if you added it via bcdedit.

P.S. - I know this thread is a couple of weeks old. -- info above accurate as of public beta build 63.
Yep. EasyBCD currently neither supports the creation of VHDs nor does it support boot menus with VHD entries already in them.

Soon enough it will, though.
