Yes,  except when you want to VPN into another network from your host, and
have your VM's accessable on the corp LAN.

In VMware workstation 6.5, use menu options, Edit, Virtual Network Editor
which open a dialog allowing you to edit.

- Select the preferred network for bridged mode.   Mine has ( eth0,
wlan0, pan0, Auto )
  where auto is then configured seperately to pick either  eth0 or wlan0

- For host-only and NAT networks,  you can pick the network address, 
and enable
  a virtual DHCP server for that net

You can have  multiple host-only or NAT networks,  and select which
machines go
on each.

In addition, it appears that each VM can select 1 of 10 'custom
networks'  /dev/vmnet0 thru
/dev/vmnet10,   which is in addition to the  host-only, NAT, and Bridged
modes above.

I think the custom devices may be used with 'Teams'  where multiple VM's
can be started
and stopped together,  each with custom networks.   The virtual networks
can have bandwidth and
packet loss programed to simulate actual WAN conditions.

So yes,  just use Network editor to specify which host NIC to use for
each network you setup.

Note,  if you are hosting multiple servers on 1 host you really should
be running the free
VMware ESXi 4.0 server  as it shares common memory segments between
VM's, and avoids
the overhead of a base operating system.  Much better graphical network
editing tools as well.
We just talked about this at PLUG West,  you can see my screenshots of 
ESX ( and Vsphere )  link
