[Openvpn-users] Multihomed?

I have recently setup a private home network based on the infamous 
linksys wrt54gl router. The network consists of my home machine, the 
wrt54gl router (as a gateway and a dhcp server) and my laptop. Since the 
router bridges it's Ethernet and wireless interfaces all 3 devices are 
part of the same IP network - which is nice :)
On top of this I also want to setup a VPN on the router and add it's tap 
to the same bridge. The purpose is to bring a couple of external 
machines into my home network.
The tricky part is that I also want the laptop to be on the VPN so that 
it remains on the network while I travel around. As I understand it my 
laptop will at all times be on two IP networks: the current physical  
network and the VPN. However when I get back home each nigh the current 
physical network is provided by the wireless access point of my router. 
So my laptop will suddenly have two interfaces with IP's on the same 
network. I heard this is called to be "multihomed". My question is will 
this create any problems for me or things will just work?
