There is means of doing this. For Wired -> Wireless there's relatively
straight forward ways to deal with it but you need to have support for
the handover across the entire network infrastructure, it's not really
something the host does on it's own.
There's also 802.21 which in theory could make this work for most
comms media wired/wireless/bluetooth/WWAN etc but even though it's
been about since 2008 I'm not aware of a complete implementation of it
and again it needs infrastructure support.
