One transmitter and multiple receivers? Just do it.

If you need to be able to choose which one you talk to, include an "address" in the data you send out, and have the receivers read it?

There may be a way to do that built into the library - I haven't used vw (I use my own RF protocol, which is likely inferior in every way except that I understand it :-P - the whole mess is in my github if anyone wants to point and laugh). No matter what, any means of "addressing" specific receivers over 433mhz RF is going to involve either a device address, or changing the lengths of the bits such that all except the target see gibberish. The device address is a vastly more graceful method ;-)
